I think the episode pages can have a change, about the weapons were used in any episode, because if the reader wants to know what the weapons used in the episode of his choice he will need select every weapon from the Armory to know what appeared and what didn't.
(Sorry, my grammar it's so much bad xP, I'm brazilian)
Alright you know what, here's what I'll do. I can see that it really is Deimos who is waving, but again, it's an easter egg. I'll include a little blurb in the Trivia section, let me know if you are satisfied with it.
