Pretty sure that it's Bigby the one that's going to be set up next
Of course, we all know that Crane isn't the one who did it, but I think that the discovery of his sexual fantasies is going to be looked upon as a petty attempt of Bigby's to arrest Crane or throw him down the witching well in the next episodes.
The evidence is placed in such an obvious manner that even the most dimwitted fable would assume that Crane couldn't be so reckless and end up suspecting Bigby instead. They're going to point out the ripped dress, the Huff and Puff stubs (Crane apparently doesn't like smoking, so we can assume that he doesn't have a reason to smoke), his reputation of eating people and being generally distrustful.
There's also Crane telling Bigby that it's more likely that Lilly and Faith's deaths were due to someone else trying to get to him due to his violent behaviour if you roughen up Dee, thus we can imply that he knows something that we don't through the Tweedle brothers' findings, something about the motivation behind the killings.

Thinks that's possible crane broke bigby free because if murders continued while he was in jail prove wasn't him so breaking him free is only way to keep suspicion off himself

Should be noted that I'd say the ginger guy was spying on Bigby and Snow for a superior to try and frame Bigby himself.
Either way yes, I have a feeling that Bigby will be the next one to get framed.
