I agree with you, I just wanted to offer a few pointers:
+ Toph is dead, so unless she taught her daughter the lie detection ability and she's in a good position to teach Korra, Korra's not going to be able to do it.
I can understand you might think Toph is dead because the first episode of season one Katara said "Aang's time has passed. My brother and many of my friends are gone." (sidenote: we've learned that Sokka has become chief and he's died within the past 15 years). "..many of my friends are gone" doesn't necessarily mean Toph was dead.
Season 3, episode 5; Aiwei and Bolin have a conversation about Toph on the tram:
Aiwei: That statue honors the first metalbender, Toph Beifong, who expanded the possibilities of what benders were capable of. Here, everyone is encouraged to reach his, or her, highest potential.
Bolin: Does Toph live here? Are we going to get to meet her?
Aiwei: I'm afraid not. She would visit from time to time, but years ago she left to wander the world, in search of enlightenment. No one has seen her since.
Season 3, episode 5; Opal and Bolin have a conversation about metalbending and Toph
Bolin: Sorry. I wasn't really thinking about all my mustaches. I'm just frustrated. I've been trying to metalbend and I can't figure it out. Don't tell anyone, okay?
Opal: Why not?
Bolin: Because it's embarrassing. This isn't the first time I've tried, and I've been wanting to metalbend ever since I heard about Toph. Your grandmother is my biggest hero!
Opal: My mom grew up learning from Toph. Just go train with her. Stop being so scared.
And again in the same episode while Lin and Su are talking:
Su: You're probably right. Mako told me that you're an excellent police chief. Republic City is lucky to have you. I know Mom is proud. [Lin looks at Toph's statue for a moment.] Can we move on? I'd love for you to be part of my life again. There's plenty of space in the house, and the kids would love having their aunt around. I do need a new co-director for my new dance performance.
Everybody speaks of Toph in the present tense. As far as they (and we all hopefully) know, she is still alive. Considering this season is going to focus on the Earth Kingdom, I'm willing to bet we'll see her (or get another mention of her) again.
I don't deny that this Toph mutherfucking BeFong we're talking about, I just assumed that Katara and Zuko were the last two members of the original group. I could be completely wrong on that account, and if so, may Toph Earthbend me into a wall. Repeatedly.
Katara could have met many more new friends since her youthful days. She could have been referring to those or other war-companions (like Smellerbee or the Swamp Waterbenders). It doesn't necessarily have to refer to her best friends. Her husband and brother are gone, that's for sure. Katara is quickly realizing at her old age that she's becoming a lone survivor again.
That said, we *did* seeagain, butIrohIf we see Toph again, she'll most likely appear as either alive or as a spirit in the Spirit World.he was dead.
Which does beg the question. In the event we see her (if ever) in the Spirit World, would she still be blind (ie, have the cataracts?) In fact, that raises an even larger question. If you were disabled/deformed in the living world, would your spirit self be disabled/deformed in the spirit world, or would the spirit show you as you would have looked like without the disability/deformity?
People have thought of the same thing when it comes to the heaven afterlife. But I don't see the Spirit World as the afterlife (especially since you can meditate there or just walk through one of the portals). Do you think General Zhao would end up in the same afterlife as Uncle Iroh if that were to be true? I see reaching the spirit world through meditation is just a state of nirvana.
Anyways, to answer your question: no. If Toph were to reach the spirit world through meditation, she wouldn't have her earthbending. If she were to go through the portals, she'd have a better chance to "see" with her earthbending, but that's it. I would love to see another Toph and Iroh reunion:)
+ Can't Bolin or his brother lightning bend? Surely Korra could simply ask him if he knows how to redirect lightning and show her a few tips. Zuko's probably too busy to teach Korra that trick.
Considering Uncle Iroh, Zuko, and Aang have been the only ones to have shown to redirect lightning, I think it's easy to say it is a firebender exclusive move (so Bolin, being an earthbender, wouldn't be able to do it).
Uncle Iroh only invented the technique from watching waterbenders practice their bending and was inspired by it. He never specifically say that waterbenders could redirect lightning.
Mako can lightning bend, but so far in the three seasons of the show, we haven't seen anybody redirect lightning. Considering lightning bending has become a little more popular since TLA days, but we're not certain about redirected lightning. It would make sense if they did learn it, but we aren't certain because we haven't seen two firebenders fight using it.
Hmm I wonder if Combustion Girl can lightning bend through her eye tattoo (or lightning bend at all). Considering "The Terror Within" battle we saw that she could curve her shots, that would make lightning bending in her hands even more dangerous.
From the early trailers of the third season, there are 2 pictures that have yet to happen, and considering there are 4 episodes left, I thought we should take a gander:
From what I can tell, that is Korra airbending the sandship and possibly Asami at the rudder. The other two people, I don't know...hopefully Bolin & Mako.
Still in the desert, maybe from the same episode as the previous picture. Korra using airbending to destroy a piece of rock. Enemy or another sparring lesson (haha I can just imagine Toph calling Korra twinkle-toes)?
It may take a long time, but, I was just thinking: If the Red Lotus isn't disbanded now, imagine if a future Avatar is born within the Red Lotus kept in secret?
Sand, Metal, Meteorite, Mud, & Lava bending...a master Earthbender is an Avatar in of itself. If they ever discover liquid metals, like mercury, then that would be interesting. I wonder how magnets will truly be put into play against/for metalbenders?
Edit: To anybody who believes Suyin may be a part of the Red Lotus, here's some fuel for your fire:
