Riggan takes Mike on a little stroll for some coffee so they can talk things out.
They talk about popularity and respect and prestige, but they never see eye to eye. Both have a lot at stake in the play but they think the other is self-centered and full of ridiculous sentimentality.
Instead of coffee, Mike walks into a bar where they drink some whiskey as the conversation continues.
Just as Mike says that no one cares about Riggan, a family comes up and asks for a picture. Mike takes it for them, very begrudgingly.
Then Mike walks over to Tabitha, the only New York theater critic that matters. Her review can make a play sink or swim.
But Mike isn't scared of her. She'll only give him a bad review if he gives her a bad performance, and he's confident that won't happen.
Riggan walks back to the theater where he finds Sam. He starts by being nice, thanking her for everything.
Then he smells pot. Then he finds pot. He gets mad at her, thinking that she'll be too high and ruin the play for him.
She tells him that his play doesn't matter and that he doesn't matter; he's irrelevant and so is everyone else.
She stops but it's too late. She leaves and Riggan is left, alone and sad. He picks up the joint and smokes what's left.
