1. He begins copying the brain patterns of anyone who wears him as a suit of armor. His personality also begins to bleed over into theirs. The very first thing that bleeds over are his feelings for Cassie.
2. He was worn briefly by Kang the Conqueror (AKA Nate Richards' future self) after the Vision programming was downloaded into the armor. There is a part of him that is an evil world-conquering crazy-pants murderer.
3. He loves the Beatles.
4. He would literally give anything to have Cassie back alive again.
5. Talking to Wanda is super-awkward because he has the memory files of the original Vision. He knows everything the original knew, including what Wanda looks like naked and sexy.
6. He has only barely restrained himself from pummeling the various incarnations of Iron Man that have come out of the Pod Caverns. Barely.
7. He strongly dislikes all of the Pro-Registration heroes, not just because of their policies and because they threw one of his friends in what was essentially Azkaban prison, but because they cannot seem to be bothered to keep track of Cassie Lang even when she turned to their side.
8. He feels terrible about Kawalsky's death, but he'd kill Shiva again in a heartbeat. He also feels bad about that.
9. That red diamond on his chest? That is in fact a hole in his uniform. He put it there to try to get attention from Cassie.
10. He has never sneaked into Cassie's room to watch her sleep. All of his stalking took place while she was conscious. A guy has got to have standards.
