They reveal themselves to be collaborating with a group to stop any Wesen threat just like her and attempt to recruit her services, offering her a home of people with the same goal.
Abe Tucker (James Martin Kelly) then has Clay go to the fight and in an aggressive manner, and superior Wesen power, knocks out his opponent.
In the spice shop, Monroe (Silas Weir Mitchell), Rosalee (Bree Turner) and Hank (Russell Hornsby) are still discussing a solution to Nick's powers when Bud (Danny Bruno) appears and asks about Trubel, as the Wesen community is now confused and all in a panic after the events at the wedding.
At a new police murder scene, the victim dragged out of a lake is one Bobby (aka Robert 'Bang-bang' Moore), a petty criminal - the boxing-mad previous blackmailer.
The suspicious coach Kingston, sets Trubel up with a nearby female boxer, easily double her size, to check what she's capable of.
When they find out they go off to confront Kingston (Stan) they first discover they have a new victim - it's Abe, who's been thrown off a roof but sporting the same puncture wounds earlier found on Moore.
Inside the gym, when Clay confronts his mother and admits that he no longer wishes to keep fighting matches, in a shocking twist of events, his mother admits she's behind hiring his coach and trainer; she then suddenly woges, smashes a nearby wooden chair and viciously beats him with a broken off chair leg, insisting that he needs to continue doing what he was born to do!
A surprised, totally crestfallen yet angry Clay ultimately stands up to her when Trubel comes to his defense and tells him he doesn't need to do what she's forcing him to do as now both Abe and Kingston are dead.
