It's as though Roswell's been drinking too much coffee - we've had three weeks of relentlessly-paced action. It's cool.
Valenti's life gets worse - especially now it appears that something really is up with Grant, and the sexy FBI agent is watching him like a hawk.
The trip to Arizona to find Laurie's family is great. Who are these horrible people? Why does Laurie's grandfather look like Michael?
It's all sooo exciting. All this mystery, and a blue crystal too.
This week's love:
Maria: Her sexual chemistry with Michael is still fizzing.
Michael: Intrigued by Laurie. Which is odd as he might be related to her.
Valenti: Maria's Mum's great, but is that female FBI agent simmering away?
Liz: Fascinated by naughty Sean.
