Eh, most of the thread's dislike of Alric is based on conversations with Egrimm- before that, there wasn't much of an opinion.
The thread likely wouldn't have *liked* him, but most likely it would have just resulted in only spending one action talking to him rather than the, what, *four* we did with Egrimm.
It would have probably involved some posturing as Alric would likely attempt to assert control of all the wizards, including maybe Mathilde herself, but I can't see it progressing to murder unless he became a clear and present threat to the expedition as a whole. Which is unlikely.
