Original Commentary
For Kimberly, it's not the thought of her mom having a date that scares her. It's the thought of Ms. Taylor's date being younger than Kimberly that does.

Modern Commentary
So, seriously, who was it? Who does Brisbane even know that isn't from the theatre?
We might have been thinking about setting up Mr. Taylor here, but decided not to debut him until year three. That would explain how he might look familiar; Brisbane might have seen him in photos or just through family resemblance to Kimberly.
Or it could've just been some random guy that she was seeing casually, and Brisbane was mistaken about having seen him before. - Terrence
