“You know how much I love you,” she tells Sal in the above clip. “I don’t know if I could ever tell you how much it’s meant to me that you let me stay with you when I first came out here, and you drove me to my auditions, you helped me with my wardrobe, made sure I was taken care of. You made my family feel like it was okay and safe for me to be out here on my own.”

After she tells Sal that she’s paying his kindness forward and giving him the elevated home he’s always wanted, she then gets to work alongside the brothers to make the home feel a little less “grandma,” as Sal puts it, and a little more modern.
