Welcome to the Nerd Farm!

The indomitable Granny D struggles with a life change as well; the move from sunny Oklahoma to live with Mike and Kim in saturated, caffeinated Seattle leaves her distinctly unbuzzed. Then there's the on-air unraveling of Mark and Chase's marriage (I'm tired of living with a Nazi!), with Joanie handling the technicalities of dissolving a legally nonexistent union. Equally traumatic is Uncle Duke's change of status, emerging from a months-long stupor to find himself pulling down six figures as a K Street lobbyist-and reregistering as a Democrat.

Also shifting kin groups is B.D., who reluctantly joins PTSD group therapy, where Dex, Kurt, and Jason call him on much-needed 'tude adjustments. But there are signs of improvement: I didn't explode! he exults, after finding Zipper living in his office. That homeless yet ebulliently overoptimistic undergrad is deeply smitten with Alex, but is dangerously far ahead of her--picking out their future tabloid nickname before she even knows they're an item. Understandably, her considerable attention is focused elsewhere--on surviving MIT's killer grind and on the Battle of the Bots, a high-tech smackdown where she unleashes Alfie, an impudent, high-end hoverbot. Bring it, techgirl.
