Question: Why did Frank's co-worker (whom he sent flowers to) file a sexual harassment complaint against Frank, when she appeared interested in him?
Answer: It's been a while since I've seen it, but I believe it's because he went behind her back and found out her address without asking her first, which probably came across as a little creepy or stalker-ish to her, even if he didn't intend it that way. It's weird when someone you don't know finds out your address or phone number and contacts you or sends you something.
Answer: Ethan's briefing said that IMF had "learnt" that Cobalt was en route to the Kremlin to destroy his identity records in the archives, at a specific time right down to the minute. As having IMF present to frame for the bombing was part of his plan, it is likely Hendricks leaked his own intentions to IMF knowing they would send a team to retrieve the records. After Ethan has his ID scanned, Hendricks turns and walks away like he was waiting for them to arrive, and may have scanned their frequency.
