Original Commentary
When Jake starts talking about Ms. Taylor, this is the only way to shut him up - Terrence

Modern Commentary
Jane's description - and I usually don't write these down - was "Jane is Jake's sister. Same species. Wears an work apron (not frilly). Slightly heavier than average, but considerably less so than Jake. She's friendly to Robert. Robert has a crush on her. Jake can be seen in the background, he's still going on"

I obviously hadn't worked out the whole Robert/Jane situation at this point.
Yep. Jake will insist that he left Lemon Technology on his own terms. But also he'll rant about Ms. Taylor any chance he can. So I feel comfortable saying that he was indeed fired. - Terrence
