"Do we have, anywhere, any indication that Brady didn't visit, or is it just the lack of mentioning him doing so that makes you think it? Because absence of evidence is not evidence of absence."
On the other hand, Chaz isn't absolutely sure whether Falkner's visited him before or not. And it's possible the visit he's remembering, didn't happen, and he's not remembering the one that did.
So just because Chaz doesn't remember a visit from Brady, does not prove for sure that Brady hasn't been there.
Well, when he mentions it to Daphne, she doesn't correct him. Just says that "it's not about him". I would think that if there were visits Chaz didn't remember, then Daphne would mention them and not let Chaz go on wondering.
