Yes, Emily knows Brisbane's name. She just really doesn't like him - Terrence

Modern Commentary
How did Emily even find Kimberly? She's not on speaking terms with Brisbane. The rest of the cast - Robert, Richard, Sinclair, and Ms Taylor - don't even know that Emily exists.
A real friend just knows. Emily has Kimberly-senses.

So, where is Emily off to? Back to work? Inviting more people to the picnic? Is she getting her own lunch?

Leaving because Kimberly obviously isn't in the mood to hang out?
Definitely not. That would require a level of awareness that Emily lacks. - Terrence
