I think that, when the split comes, part of the end of contract deal will be three or four (very bad) films for Katie made/backed by Tinky's studio. These, combined with any roles that are tossed her way due to the renewed interest in her now single life, will be the perfect excuse for Slurpi to live with Tinky('s sisters). Katie will be made to look like a workaholic, he will be papped regularly looking like a doting dad enjoying joint custody and by the time the run of bombs movies comes to an end the public will be that used to seeing Slurpi almost exclusively with Tinky and not Katie they won't be as inclined to question the true equality of the custody arrangements.
