.. Got to love that on the voice bloopers reel!
I've watched it far too many times. Anyway I posted caps of what happened moments before the diving clip.
The top caps happen just after Leon says "Catch you later" to Angela. It took me a few viewings to see that Claire rolls her eyes at this. Tut, tut. The bottom left cap happens just as Angela calls Leon back. Claire looks mildly amused. However just as Leon is turning around he tries to make a bit of eye contact with Claire but she looks down. Then the "flare" begins!.
Clip of Resident Evil 5 before the blooper.
