Touched by his boyfriend's support, Mark gives him a kiss and then with a heavy heart gives him a talking to. If he want's this job, he can't be expanding, growing and breaking the building, as that's how he lost his last 2 jobs. And since both those time involved the mop headed fox, it's best to go right for the source.
It's not that he doesn't want to grow, just no during work hours. Kyle understands.
