It would've been nice if instead of Carver being the antagonist, it was Roman with a whole new group trying to seek out Shel for what she did to the diner. There could've been some story potential there.
Wyatt. The group needs more comedic relief, and Wyatt is the perfect guy for the job. His general laid back attitude coupled with stories from his past about Eddie and all the time they spent getting high would be gold.
"I cannot be caged. I cannot be controlled. Realize this as you die, ever pathetic, ever fools!"
You know, I think if Shel and Becca were with them, then Shel would also be the one to have some experience with babies, which would leave her to help Rebecca give birth to AJ with Kenny. Vince might have some experience too, I believe, since he had a younger brother. I don't think Russell and Wyatt would have a clue since they never mentioned having any younger siblings. (That I'm aware of).
