When Grant is dancing in the tub, his pant legs are pulled up over his calves to keep them dry. But when he climbs out a moment later they are down to his ankles.
When Becky exits the hotel room after her bidding appointment, she passes Ian in the hallway, and he is then called in to the hotel room. Later, when Arby is looking at the list of bidders, Becky's appointment was listed at 3:15 and Ian's was at 4:15. Ian would not have been waiting to be called so close to Becky's bid appointment.
While Ian is waiting for his appointment in the hallway, he remarks to the Jimmy about how he is nervous about meeting his online love interest. Meanwhile, Becky exited the room before his name was called, therefore it is most likely that he was already waiting in the hallway to ensure he was not late and would have heard Becky's name being called by Olivia.
