In doing so, you’re making up something that doesn’t exist. The cross-claims do not assert a loss caused by a breach of duty, nor do they allege resulting damages, which is what I just tried to outline for you.
Only the original claim by LK and the counterclaim by MB are actually suing each other. SGF and RC are not suing anyone.
Edit to clarify: LK is suing MB, RC, and SGF. MB is countersuing LK. SGF and RC are suing no one.
