So, I've played in a DH game recently where my Psyker finally used his psychic powers enough to draw Perils much to the detriment of the party. I already know how to handle Psykers with the regular "joes" of DH. My question comes in DW when a Librarian manages to draw Perils, or even Psychic Phenomena. He's a Blood Angel and taken Rite of Sanctioning Talent, allowing him to choose the Phenomena that occurs (in his case, bleeding walls).
How would the other Battle-Brothers react to something like that? How would they react to him drawing Perils and causing harm to the group itself? I doubt they would outright attack the Librarian (as did some of my fellows in the DH game did), though I do have a Black Templar player that could provide some conflict.
