Under Reilly, IIRC, Tony was retconned to be Stefano's son again so, yes. When Tony came back under HS he was clearly not Stefano's son once more and, as a personal favor to me, Tony even mentioned Renee in a "Dimera family dinner" scene. (Yes, I'm kidding about the personal favor to me. Tony & Renee were my first 'ship. That retcon burned me.)
Shameless doesn't cover it. Couldn't they just have had Ben have a twin? Plus I'll never forgive Ben for not making Abby his first victim. There's his insanity defence right there.
I like Jack, I really do. But I wouldn't say the audience had formed a bond with him in the 3 months MA was in the role before the rape. Jack gave off a stalkery vibe at first, then it was an "I love me so much Kayla must love me too" vibe that set up the inner conflict. Jack raped Kayla to punish her, then he forced her to play the role of his wife while he psychologically tormented her, etc. He never paid for his crime. That doesn't mean I don't like him, it just means the character commited a rape and never paid any legal consequences. And I will never, ever get over the utter BS of Dr. Tom Horton telling Jack he should ease up on himself and realize he was worthy of marrying the town virgin. (I'm paraphrasing, obviously) because even a noted rape apologist like Dr Horton (see Bill Horton's rape of Laura) wouldn't go that far and, even worse, it removed the inner conflict that made Jack an interesting character.
Word to the power of WORD (TWOP reference) on the "redemption thru rape" trope. Sami is my girl - she's a very shouty girl right now but I'm in her corner - and the fact that this show has had her raped TWICE and, for kicks and giggles, had her commit a rape, is just beyond gross. All three events were just plot point BS but the EJ/Sami stupidity was all about making Sami suffer enough to make her worthy of Lucas after the Stan stupidity. (Pardon me while I vomit in a corner.) I was never a huge Sami/Lucas fan but I didn't hate them, I really liked them in the very beginning. The appeal for me was that Sami didn't need to be "worthy" of Lucas because he was a little schemer himself. They understood that about each other. The whole blackmail rape in a car was dumb.
