It looks like 47 is sitting near the parking lot.
Maybe he wasn’t invited to the party and we will have to find our way in / invitations and target the ones who dared to scorn him. Who would dare, they don’t belong, he does !
And I really like your take @apricotbones, always kin on more Diana/47.
(I also don’t remember who said it, but someone once mentioned in the bonus mission wish thread how we never had a reverse forteress : hostile in the perimeter, safe/public on a select area on the inside)
Edit : found it, it was @CNC
