Jennie about Luke: "I was really happy that he was coming back, actually. I was excited. It felt right, you know, it felt like “where’d you go? Why’d you leave in the first place; here you are”. And, um, we were very happy to have him back. And I’m, you know, he’s one of us, you know, he’s like family."
