It's a bit rude when someone makes a comment like that immediately after someone is more-or-less insulted in some way. You have to let the person take in what they've just heard and process it themselves and let them speak about it when they want.Why was that a douche move? Thought he was being cool allowing for him to respond to the accusations.
It reminds me of a scene in BB05 I recently re-watched. A similar thing happened and an actual argument ended up starting because someone asked another HM how they felt after being criticized in a goodbye video while still on the couch straight after it finished.
That's just me though.
