You and him were partners and didn't know each other's identities, but you really had a thing for him and he knew cuz you flirted with him alot but he rejected you because you had to keep your identities a secret, one day you both where taking a brake and you decided to tell him you had a partner to see if he would get jealous

Miguel: You have a partner. Wow, that's awesome. I'm happy for you

He smiles
