but he also came after Tony/infiltrated his company during Matt Fraction's run to sabotage things behind the scenes (for the Mandarin). for awhile everyone was trying to guess which supporting cast member was Sinclair. i guessed that it was Bambi Arbogast because she came out of nowhere and kind of looked like Ms. Doubtfire. but it was some random dude who kind of looked like Phillip Seymour Hoffman. he was in a relationship with a gay member of Tony's new company. he exited the book by making a video apologizing to guy he was semi-dating and blew his brains out. it was a really weird subplot.
