I replayed this elusive target (I have it on steam and PS4) and I took my time…
Faba when returned to the presentation (guns, bombs and whatnot) on his way there he called a woman; called Alice. While he was speaking, he said to her, that he sent an invitation to the ICA, but he didn’t wanted to be poisoned again by their top agents, he wanted 47 himself. Then he mentioned, that 47 might be a myth but he really wants to meet with him.
I hope, this means, there will be a small story with him.
So I think when he comes back for a 3rd time, he’s going to be an enforcer. (as in now he’s going to know everyone in the building…or at least in the briefing area)
