Aaron couldn't accurately gauge how well things were going on their date because Keeley was giving off very mixed signals. She wasn't openly hostile like before but she also wasn't making any effort to keep the conversation going. She answered direct questions and that was it.
At least she seemed to be enjoying the food. This was a good choice. He remembered her mentioning that she took her dad here to eat before so he knew she liked it.
He held back his frustration that she wouldn't give much detail. If she didn't bring up the fact that she had a cat, he wouldn't be able to enact his plan.
It was Aiden's second piece of advice before leaving his office after Aaron asked about it. If he asked for Keeley's help in getting a cat himself, it would show his soft side and he would be able to spend more time with her.
