My guess is that after a couple of more nights in his office, Harry's wife opened the door and let him back in. Divorce carried such a stigma about it of shame and embarrassment, especially for the the wife that it was easier for Harry's wife to try and forget about it. The wife would have been looked at like "What did she do, not please her man? or She was a good wife was she". Perhaps Sal was "scared straight" or temporarily, given the fact that homosexuality was viewed as total non conformity at a time when conformity was the norm and expected. I like how the Paul /Orson Welles story line is carrying over into this season. We got just a taste with the Kennedy Vs. Nixon episode. Especially with the neck scarf he's wearing during the party scene in addition to his new beard. I wonder if Paul is emulating Welles because of the physical resemblance and one artist (Paul as a writer) imitating another artist... imitation is the sincerest form of flattery . Or Paul looking for a way to express his own identity and this is a step towards that? I'm probably reading too much into that. I love how he apparently "borrowed" a typewriter from SC.
