Scorpion, Season 2

Walter O'Brien:
I'm sorry.

Toby Curtis:
Huh?

Walter O'Brien:
For whatever I did that made you so mad at me. I mean, I know I have relationship problems. I barely speak to my parents, and I can't date a woman for more than a few months. But I do try to be a cognizant friend to you, to Happy, Sly, 'cause we're supposed to understand each other....But if I'm making you so upset to where you're arguing with me about minutia, and I don't even know what I'm doing wrong, then I am not making as much progress as what I thought. It's disheartening.
