You was at a Calpurnia concert, accompanied by your best friend, the band's the bassist, Jack. When the show ended, you went backstage with Jack to congratulate him on the show while the other band members did other things.

Until then, you and Jack were talking, until Finn went backstage to get a bottle of water, until then he hadn't noticed you. When he noticed you, he raised his eyebrows, curious and cleared his throat while throwing away his bottle of empty water.

"Who is... your friend, Jack?" — Finn says, looking at you and then at Jack.
