acting as if nothing happened that one christmas night

After Neville told Florence how he feels, he didn't know that she heard what be had said and so now as two people who work together, things from Florence's POV gets complete, confusing and awkward. So to get to understand things a bit better they go for a beer at Catherine's. Does she feel the same? Would she tell him she knows? If so What would she say? Would it work out?
