Now, I know that this has been talked about a lot (and I’ll probably discover that someone already talked about this before) but I want to give my thoughts, as I haven’t seen anyone say this theory yet. So hear me out please.
Alright, so far I’ve seen a bunch of different speculations about what is going on in the above picture. Back before season 2 came out, I think the largest theory surrounding this was that this was proof that he was galra, as it made his skin turn purple and shows his galra form. Even now people still think that is what it is even though they don’t need it anymore to try and prove that Keith is galra.
Lately I’ve seen a bunch of theories about him also being a druid, and saying that that is why his hand looks like that instead of the glowy wounds like Shiro and Thace’s.
Then there is the simpler theories of the magic just burned his hand and the pure quintessence healed it.
All or any of these could very well be true, but consider this;
HEY IT’S A (really late) VALENTINE’S DAY SEQUEL TO THIS! You should really look at that to understand what’s going on, but as a quick backstory to this, Adrien found out the scarf he thought his dad gave him was from Marinette, it upset him too much so he gave it back to her.
And then I hated that it was just angst so I made this to make up for it? What started as a one page thing turned into a too-many-pages thing. Hence being like… 2 weeks later for V-day. Oh well! Enjoy!
