*cracks knuckles*
i have opinions.
In 11x12 Heidi tells Debbie that she's "splitting tomorrow" off to Texas to join her friends in some scam or whatever. She very casually tells Debbie that she's welcome to come and bring Franny too if she wants. I really dont think Heidi cares one way or the other.
A thing I think that should be acknowledged here, is that even if we think Debbie was considering it that day, by later that night when the hospital got ahold of the Gallagher's and told them Frank had died of covid, Debbie wouldn't be going anywhere, and Heidi would definitely be outta there ASAP. (Not so much because she's uncomfortable or whatever, but because she has her own plans and she does not care enough to change them.)
So even if we assume the Gallaghers don't really bother to isolate for covid exposure (which like i dunno, maybe they would be good about it but its besides the point), I think that Frank's death would bring all 5 of his kids (yes Ian is one of Frank's kids) together in a stronger way than what we were seeing in most of season 11.
Okay bear with me, because I know they didn't like him, often hated him, (though Liam was young enough to still be pretty fond of him just like we saw with Debbie and Carl), but they would still feel his loss. They had feelings about it when Monica died, and she was the parent who was gone for huge chunks of their lives. Frank was actually around most of the time. And they all had their moments with Frank (except for Ian i suppose though i maintain they both still considered each other father & son) which would make their feelings about his death even more complicated than Monica's (I guess like how Ian had more complicated feelings about Monica's death because he had been closer to her as apposed to the others who were closer to Frank).
So all of that is to say that I think there would have been some emotions and they probably held a memorial party for him at the Alibi much like they shared some memories and partied together after Monica's funeral.
Frank had just told Debbie that the only way she was going to find someone to be with was to find someone who was a bigger loser than her. And I think we're supposed to assume that she's taken that to heart and that it contributes to her bringing Heidi home with her.
But like I said, Heidi definitely woke up the next morning and skipped town. And I really dont think that she nor Debbie really cared about it.
I think within the following days that Debbie would have ended up in a heart to heart talk with Lip. I dunno if yall remember, but Debbie and Lip are actually pretty close before season 11? Their butting heads over the house situation wasn't going to last forever. She would have told him what Frank said to her and he would have done the big brother/pseudo-father thing that he normally does and tell her about how it's bullshit, maybe he'd even have a little advice for her. I think whatever is said between them would have helped her understand that Frank really was just full of shit. And going forward she would not be looking for someone "more of a loser" than she is. 😑 Maybe she would even look for someone who really has their shit together? Debbie is a catch tbh, and I think she can very much achieve a good relationship with someone stable. She's young, she has lots of time to learn and develop better relationship habits.
And yeah idk, I just think they'd all be making a slightly bigger effort to connect after Frank's death. Especially for Liams sake, you know?
Uuhhhmmm okay I hope I answered all your questions in there somewhere.
Oh...
No, Debbie did not lose any more toes. 🙏
