Melrose Place Spoilers: Season-end spoiler

I know Melrose Place spoilers have been few and far in between but this spoiler's a good one! It's not just  spoiler for any episode... it's for the season finale (or perhaps the series finale -- no word yet on whether or not the Melrose Place remake has been renewed  for a second season).. check it out and see for yourselves!

Question: I’m having Melrose Place withdrawals! Please help me! —John
Ausiello:
The season (or is it series?) will end with a shocking arrest. Feel better?

You guys have any idea who could be arrested?
