Silent member of an LLC and taxes?

25% member of an LLC, but not on paper (I know I know, bad idea). Basically two people formed an LLC 50/50 and then one of those two people has agreed to give me 50% of their cut without the other one knowing. Outside of all the comments I'll get about that structure, how will this work come tax time? Will I have to consider the person paying me 50% of their take my employee?
