Season 2 Episode 1 The Core of it

"I'm wearing pink today, Cal, pink, because I like pink it makes me happy, which is something that I have not been for a very long time! I'm divorced and I'm free and I'm happy and if you do something to screw that up…

I won't! I promise I won't!"

"Oh, I hope not, because it sure feels like you're starting to"

"Hey, come on have I ever broken my promise?" Lightman asked with such an innocent look on his face it made Foster mad.

"Cal, don't you dare ask that question!" she even sounded threatening.

"Come on Foster, you're don't you think you're overreacting? It's only money and we finally got rid of Zoe! Isn't that what you wanted?" he continued to push her even more mad.

"Yes, Cal, I'm sure you did it for my sake… and I'm also sure our employees will see your point when their pay check won't be coming this month"

"I'm sure you'll figure something out, you're a smart girl".

"Oh, don't you dare put this on me, this mess is all yours this time"

"Come on Foster, remember the employees, they have no part in this. But if you insist, I'll find a solution" Lightman's eyes twinkled and that made Foster regret she even had that conversation with him. And much to her worry he continued while he turned around to leave her in the hallway

"You know push comes to shove I can always go to Vegas make the money back, so…

Wait! Don't even joke about that! Cal, promise me you'll never go back to Vegas!"
