Could be Billy? Would make for some angsty deja vu if another guy who Red knows ends up dead, and she’s the main suspect. She’d probably believe she’d done it, given what happened with Peter.
Yes, I could see this easily happening, despite how sad it would be for Red to go through all those feelings of guilt again. It would be a very effective story-telling device though, since Adam and Eddy said in their most recent podcast that Red’s fairy-tale story will pick up from right where it left off in 1×16. Last we saw her, she’d just killed Peter and she and Snow White were on the run. We’ll likely see Red deal with her guilt as she meets fellow shape-shifters and the wizard who gave her her enchanted red cape. I think they’ll help her come to terms with her identity and help her learn to control her shape-shifting. I think this will parallel Red learning to control herself all over agin in SB now that magic is there. I wonder if we’ll see the good wizard who gave her the cloak in SB or if he is stranded in the EF. If that good wizard is in the EF, perhaps Belle will convince Rumplestiltskin to make Red a new enchanted cloak. There are pictures of Belle and Red together at Granny’s which suggests they’re becoming good friends.
