Dazai is putting on one of those red handkerchiefs along with a hat and coat he stole for good measure as well as covering up most of his face in bandages to hide his identity. Upon entering the base, he will immediately attempt to spread confusion, misinformation, and distrust by presenting himself as an injured guard from the battle Alrys just escaped from and spinning wild stories about how Beckett is the traitor, actually, and tried to kill them all because Max had found evidence of his treachery, and how Callie has been compromised by the enemy -- he saw her shaking hands with an outsider from another city bubble!!
He'll also try to claim that he found the base camp of these intruders and can take Alrys to them to wipe them out if they'll bring him to her, and if he's successful in being given an audience he'll start staggering as though dizzy and seemingly "collapse" from his injuries, with the goal of "accidentally" falling on her to nullify her power or even letting her catch him if she's loyal enough to the people on her side to help them.
He has a gun tucked into his waistband and a knife up his sleeve, if this goes sour.
