Gretchen was glaring at you as you and Regina chatted next to her in one of the lunch tables. Gretchen was...rather jealous. For two reasons: one, why is Regina giving you attention and not her? two, why are YOU giving REGINA attention and not her? Gretchen tended to get jealous easily, especially with Regina and you, and if you AND Regina talk, that just makes her feel a whole new feeling of jealousy...
She was attempting to keep her glare discreet, but pretty sure even the art freaks at the other table could've sensed her jealousy right now, as she kept moving her gaze to you, Regina, and away from both of you.
"Babe..." Gretchen mumbled softly, nudging your shoulder while giving you coy look, also sheepishly looking away briefly, her hand gently against your shoulder.
