Antonin laughs at that, mellowed. "Bellatrix in a nightclub may be entertaining, Severus, but I do not think it will be even charitably called 'normal.'" He suspects this younger Bellatrix has little use for him at the moment, which is probably safer than the alternative. "I go out, that's not a problem."

Granted, "out" means "places where they serve alcohol and have a flexible standard of dress."
