the prenup is good enough i believe. heard she gets 3 million for every year she stays married until the fifth year of their marriage. and this is the fifth year so time's up. something like that. taking child support is the next step. this is another angle one can look at.

worst possible scenario for katie: she gave up a career to marry, then lost her husband, lost the money, and if all goes really bad she'll lose little suri for tom to send to the cult as mentioned here:

course these are all just baseless rumors. but city center is still closed, euro is finished and there's nothing else to do.
