Oh I know, but on a serious note it's about the only thing that makes sense to me. Steve's body starts rejecting his new kidney, he tells the guys, they obviously want to keep him as a member but until he gets shit straightened out with his health then no one really knows what to do so no one says anything about it. Meanwhile the band continues doing dates they have to do, etc. If no one really knows what's going to happen, no one can really say anything. Right? Sounds pretty feasible to me.
