Ophelia and Alexei
"No date. It was just me." Because that was true. "Laertes has not fixed things yet." Also factual. She had no date because no one had been interested in going with her, and Laertes was working on something new that hadn't yet been settled.
"Crowded I guess?" Because that was only logical and she could tell from the amount of noise if nothing else. She doubted he was any more a fan of crowds than she was, so it would be a reason to come out for air.
