I repeat what is said in my previous intervention. Mc, it seems quite realistic to me ... The doubts present in his head seem to me in line with the thoughts of the great majority of people, in any situation (not necessarily on sex). The continuous waiting for something to happen between him and Abby, considering the relationship with the deceased wife, I find him adequate (even if he does not respect the canons of the AVNs). The only thing, which I would find intriguing, would be if, one of the secrets held by Becca, was Frank's natural daughter. Unfortunately, I found enough data, to eliminate this hypothesis. Becca was born in March. To return to conception and subsequent pregnancy of nine months, it should have been born in January, or, at most early February. All this, I deducted it from Frank's flashbacks. When Shannon left him, and Jessica went to the room, to console him. According to the dialogues, it had been in the room for a month, and summer was coming. Of course, if the DEV wanted to rewrite the date of birth, it would have a great very exciting event, to be inserted. We add the fact that Frank is no longer a boy, and a biological daughter, it would be a nice event.
