Meanie Insecticons

From the episode Traitor. So um, is everyone ok with Mirage running around with a big hole in his head for the latter half of the episode? I really wasn't.

Optimus: Mirage, are you ok?
Mirage: Err... uhhh... Yes Prime, I can manage.
Cliffjumper: Yeah, he's great. 'cept that huge effin' hole in his forehead!

Tiny birds fly into hole and begin making nest.
