Archie & Open
Archie is relatively sure that no one is going to realise he was in the play. Not because he's that good an actor, and not even because his costume was too elaborate, but his co-stars were so very good, and immediately more recognisable. But it isn't as though he's here for fame and attention. The whole play has been a thrill, he's loved being involved, and he's so pleased for Ren that it's turned out the way it has.
He's drinking a coffee, watching everyone else milling around, content to enjoy the atmosphere.
