Green Tea and Hazy are close, as you can tell here. While Hazy has mellowed out since taking on the role as Prince, he still has his moments of ghetto street rat resurgence. During those times, it’s up to Greenie to calm him down before he hurts somepony. This is one of those moments.
Note: I gave Green Tea a goatee cause I can! Plus, they are kind of sexy, so I imagine Hazy would swoon over it.
