you and Jack had gone out on a date which was supposed to be just you and him as friends, but you decided to invite Stig without telling him, he of course was pised since you spent all night taking to Stig instead of him. The day after, you sat with him during lunch.

I better eat up before you invite Stig without telling me to eat too, hm?.

he rolled his eyes, obviously jealous but tried his best to hide it
