Luna and Nika left the apartment soon after Uriel stormed off leaving the sobbing mess that was Medusa to think things through. More than thinking, though, she did a lot of crying and binge eating.
Her relationship with Uriel had been rocky from the start, to say the least. It was always she the one who made the first move and she did her best to make him feel wanted, but he never showed any interest. Once she found about Water warlock's influence on him, his actions started making sense for her and she decided to give him enough space but the gap between them became bigger each day and she was forced to see how other women like Charlie, Nika and even Cassandra flirted with Uriel right in front of her.
The ony thing that allowed her to keep calm was that he showed the same amount of interest in them than he did to her.
