I imagine Barty's not contributing right now because he's on a hot date, possible mulling over in his mind whether to get dressed and leave or spend the night and grapple with an awkward breakfast.
This is like when I took rum to my mates in englefield green and one of their housemates was like can you turn off the music because its distracting and close the door, turns out they wanted to fuck. no shame really he can browse dissensus with his left hand and treat his woman with the right hand.
