John is fed up being chased and tries to escape and be a kid for a
day, taking Riley with him to Mexico. Bad idea, since he used to live
there with his mom and his face is still known. Cromartie tracks down
Sarah, Derek, Cameron and agent Ellison come to the rescue.

So, you're sixteen years old, you've taken your girlfriend to Mexico,
got her the honeymoon suite no less and just when you're about to get
it on Bam! a deathwrecking homicidal robot shows up. I hate it when
that happens.

Cromartie finally bites the dust in a John Woo-esk shoot out in a
church: bit much, but fun.

Sooooo, Jesse's been sent back from the future to kill Cameron?! From a future that's different than the one Derek's been sent back from? So, maybe, in Derek's future, there's no need to kill Cameron in the past? Hmm. My head's starting to hurt....
