Although I am quite sure Kate will vote Tim, it is a worrying possibility that he could avoid any other vote and thus escape nomination. This would happen if jonny helps jade shoot herself in the foot:

jade votes alex kate
jonny votes alex jade

The one curious permutation that gets them all up is:
alex jonny jade
jade alex kate
jonny alex tim
kate jade tim
tim kate jonny


As to Jade v Tim vote maybe that needs another thread.
