I believe you posted earlier that since CLA didnt escrow you wouldnt have sent him SDs funds. So basically you helped SD freeroll off of CLA.
When he came into the thread and told SD he would honor the bet is when he is on the hook for the money. Not before that according to what you said yourself or you're part of the problem.
That said I think I cant be sure but I think if SD had lost he would have been willing to pay. If not theres clearly no bet and CLA could have clearly got out of it, but he did himself in when he said he would honor it. Once he said that hes on the hook imo.
