Ian wasn’t sure Monica would come when he called. Ian said being compared to Monica was a compliment because he didn’t want to see her be sad. Monica said “you can never make those people happy, like it breaks their heart just to look at you” and Ian tears up because he’s thinking of Mickey.

He was lonely, and he wanted his mom to tell him everything was going to be okay.
