Harris and Dempsy:

Dempsy: Wants Claire happy. He loves her as a friend and wants to beat the crap out of Cam for hurting her but wont. Agreed to help with the plan to help Cam and Claire but mostly because he is scared of Massie…YIKES!!

Harris: Loves Claire as a sister and hates seeing Cam all sad and wants him to get back to get together with Claire so he agreed to the plan. So now Cam is going to be happy AND he got 150 extra…..YIPPY!!

So Massie scared Dempsy and paid Harris wow she must want Claire to be happy because she cares for her )
