When Michael asks his TA to help him grade papers, he didn't expect her to come looking so... hot. Athena is dressed for a date she has later. The heat between them rises with every pen stroke but it's when Athena is in the bathroom that things take a real turn. Michael accidentally catches a glimpse of a text from her friend, referring to him as "Professor Sexy"... and his sudden awkwardness is obvious when she returns. With Athena's confession of her crush on him laid out, they tread as professionally as they can - all over Michael's desk.
