Picture 1: Keith’s bed in Season 1 Episode 2.
Picture 2: Keith’s bed in Season 2 Episode 4.
You see the discrepancy?
Now, a person might (mostly likely accurately) say that this is a simple mistake by the animators and they flipped the image or forgot how they drew his room before or something. Or - OR! sometime between S1E2 and S2E4 Keith switched rooms. S2E4 also established that Keith and Lance’s rooms are right next to each other.
Now, I’m not saying that Keith changed rooms to be next to Lance…
…But maybe Keith changed rooms to be next to Lance. ;)
