Anyway...I just pulled out IC#1 and reread it.

Ray showed up at Jean's house exactly one hour after Sue was killed.

Ray mentions that he's an hour late for his meeting with Jean.

It is also mentioned that, when Ray is subatomic, his signal device doesn't always work.

OTOH, Ray looks genuinely sad at the funeral.

There's also the fact that Ray goes with the mindwipers to capture Dr. Light, as if he's one of the group that mindwiped them in the first place.

However, whenever there is a flashback to that scene, you don't see Ray there.

Curious.
