PJ isn't just some random kid I met at the hospital. He thinks he might be Jon's son. So do I. 

Rome

Katherine: Delilah, you and I know that Jon is not here because he couldn't share what he was. He thought keeping all of his dark secrets to himself was best. Obviously, it wasn't. What if we're doing the same thing? Making a huge mistake by hiding our secrets?
Delilah: What are you saying?
Katherine: I'm starting to think that we should tell the kids the truth.

Katherine: Back when Eddie was getting sober, I didn't want to drink in front of him, so after a long day, I would stop by Jon's office. This was our thing. We'd drink and share.
Delilah: I didn't know that, but I'm not surprised. I mean, Jon always said that he saw himself in you.

I got to say something here. Today was one of the worst, awful crap days of my life. It's also one of the most incredible. Because I am reminded that I have the greatest friends in the world. I love you. All of you.

A Million Little Things Season 2 Episode 6 Quotes

Rome: I know you really want to do this, but Maggie knows you from therapy, and with Gary being all upset about Colin, what no one needs right now is you asking a bunch of questions. So if we are going to do this--Gina: C'MON GUYS!
Rome: Which apparently we are, then I'm going to need you to promise me that you are going to keep your mouth shut.
PJ: I'm an awkward teenager battling depression. Keeping my mouth shut is kinda my thing.

Delilah: You sure Katherine is OK with you watching Charlie?
Eddie: Totally. She's been so supportive. Somehow, someway, we're getting there. And how's Andrew and his incredible quaff. 
Delilah: His quaff is great.
