Oscar and Angela dateing at start

Not sure if anyone else posted this but in season 1 ep 3 about 9 mins in angela said he was pathetic because he didn't stick up to micheal about the healthcare situation. Why else would she say that to him? It's also a pretty good situation for oscar cause he hadn't came out yet. micheal also asked if they were dating in season 2 episode 21 about 2mins 40secs in. also Dwight and Angela started dating 6 months ago or around then because of the redacted complaints about Dwight was 6 months ago season 2 episode 21 about 9mins 20secs in.
