Question: when they all came back from the hotel and met HKS in the lobby/elevator, wherever, was he leaving the hotel, as in leaving her alone because how could he have known when they were getting back?
The implication seems to be that HKS was surprised to meet them in the lobby, but I can't figure out why. Moe's story seems to be that they went to the airport to pick some people up. Did they return earlier then expected? I haven't puzzled out that muddle yet.
He couldn't have known unless he had a view of the parking lot from the room - or - one of them gave him a heads up cell call.
