Hmmmm. Out of everyone here, I think Allan seems the most suspicious. Droids would make more sense if this was a different story universe, but in Star Wars, they tend to fall into the disposable troop or loveable mascot categories. Finn basically just woke up in Medical and wouldn't have any idea where they're at, and there's no way Leia would be a traitor.

This is, of course, assuming someone's actually a traitor in the comic. Though it feels more likely than having a tracking device planted on a ship or an unidentified bounty hunter following them at this point. I'm not sure if Star Wars can pull off a "who's the traitor" story, but we'll see. It'd definitely work in-comic though as Jim's shown before!

Oh, or perhaps Snoke is actually tracing where the Resistance goes; the blue milk thing is just a comic invention after all. We did just get confirmation he's got Force powers with the lightning as well. Which makes me wonder if there's going to be anything visible that'd explain this set-up that could plausibly be of movie origin instead. Force mind tricks aren't exactly visually obvious, handwaves aside.
