Season 7, Episode 22: Unaccompanied Minor

"Okay, so... this is the house. There's another house where you're gonna have your own room. But that right now is just wood and no walls. So we're gonna stay here for a while. Derek? Okay, he might be AWOL, he's had a bad day, and he's a little pissed off right now. But we're gonna be fine. So we had a big plan if this even worked out. We were gonna have a lullaby from Malawi to make everything feel homey for you. To be honest right now, I can't even thing of an American lullaby. Lexie? You know, a lot of people live here. It gets kinda crazy sometimes and it's usually not this quiet. Alex? Okay. We're gonna be okay. You and I. We're a team, right? We're tough. We have that in common. I am very glad you're here. I didn't think your first day is gonna be quite like this. But, I'm gonna get it together and we're gonna figure it out."

"I always said I'd be happier alone. I'd have my work, my friends... But someone in your life all the time? More trouble than it's worth. Apparently, I got over it. There's a reason I said I'd be happy alone. It wasn't cause I thought because I'd be happy alone. It was because I thought if I loved someone, and then it fell apart, I might not make it. It's easier to be alone. Because what if you learn that you need love. And then you don't have it. What if you like it? And lean on it? What if you shape your life around it? And then... it falls apart. Can you even survive that kind of pain? Loosing love is like organ damage. It's like dying. The only difference is – death ends. This? It could go on forever."
