[@Guardian Angel Haruki], honestly, the more I think about it, Daniel won't allow a shapeshifter who means them harm to live long enough to, say, go find the nearest settlement and use his shapeshifting to impersonate the party to frame them for crimes they didn't commit.

So he'd probably work with Malcer to ensure that Bartholomew dies as soon as possible.

That is, if Barth being a Changeling is obviously known.
