Alex and Liz in “Heatwave”

It's amazing. You wanna know what? A couple weeks ago, if someone were to ask me who I would trust with my life other than my parents, I would have said you without skipping a beat. And now... now I feel like I don't even know who you are.

Alex, I want to tell you, I do, but... it's not my secret to tell. Alex, I need to know what you told Sheriff Valenti.

I want to tell ya, Liz... but it's not my secret to tell.
