But who's in the firing line for his anger?
As Honey and Jay get closer, they decide it's time to tell Billy the truth. When Honey asks him if she can have a word, Billy thinks romance is in the air and that she wants to get back together with him.
Left broken by what she says next, Billy snaps at Jay and tells Lola about Jay and Honey, quickly realising that she already knew.
Furious, Billy storms out and when Lola later tracks him down, she tries to talk to him but as Jay appears, Billy loses it.
