Dex in custody? (spoilers for latest season)

One experience Dexter's never had is being arrested, charged with one or more of his killings. I wonder if that's what the writers have in mind for the season/series finale of New Blood. Clearly Angela suspects he killed the drug dealer, assaulted another, & might even be the Bay Harbor Butcher (though the photos she looked at online showing decapitated heads were a bit ridiculous, seeing as they'd been recovered from months or years in trash bags underwater). In fact, now that she's concerned about the fate of the missing blogger, she might attribute that disappearance to Jim/Dexter. I guess that depends on whether or not she finds Kurt's trophy room.

Still, might be the end of the line for Dexter one way or another, with Harrison having at least the rudiments of the code to go by. Perhaps Dex will sacrifice himself in some way for Harrison's freedom. One week to go...
