Very painful, but it would regrow. Like it's technically part of the symbiote kind of, so it regrows if cut off, but the appendage part that's cut off is basically dead and worthless.
Also, thought I'd throw out that she's not actually wearing jeans anymore since they cut them off of her. She's wearing a skirt made of her bed blanket.
Yeah... This is true. Ah well. Maybe after she's not shocked out of her mind, she'll be able to come to terms with accepting his eggs so it won't be as scary next time.
<_<" Now that would be hella awkward too. Especially since he's gay. To be fair, I think it would be super weird for him to lay eggs in anyone, even Vin.
By the way, how do they figure out that he has Sabastian without giving away Kuznet to Cora?
I'm getting pretty tired, so I might change my mind on this a bit later, but I'm thinking we probably won't keep it hidden from Cora, only Vin. I mean, eventually, things are just going to pile up too much for Cora to ignore.
I'm thinking Cora will leave pretty shortly after they get Sabastian back, maybe even 'letting' them rescue Sabastian. Maybe this will be Coras clue to come to him, like she knows it's a sort of trade.
Edit: As far as them figuring out who has Sabastian, I'm thinking Tommy will let it slip, maybe keeping some of his own boys feeding him information even after he's left for dead.
