Even sweet rocket scientist Holly (geek dream Felicia Day), the once-killed then techno-resurrected "photonic plasma processor married to a bioprinted body," is distraught. But mostly about her incomplete memory: "Everyone's so sad, I wanna catch up so I can feel sad, too."

That's "Eureka" -- all for one, one for all. The move-out keeps them busy battling wormholes, suddenly opening up to endanger everyone, as evidenced by the mincemeat pile of pieces into which they render android deputy Andy. "Wormholes, cyborgs, endless possibility," marvels reawakening Holly. "No wonder you guys love this place."

As of Tuesday, it'll all be on DVD, and I'm looking forward to looking back with Colin Ferguson's common-sense sheriff, Salli Richardson-Whitfield's savvy doctor, Joe Morton's disillusioned brainiac turned mechanic and all their quirky cohorts.

Monday night's hour wrap-up neatly captures their distinctive appeal(s), bouncing through scientific challenges and romantic quandaries. Former friends/foes reappear in great guest cameos, and the "Eureka" writers romp through their range, from "quantum teleportation" to juvenile body-part jokes. They perhaps explicate too overtly the show's central charms -- geez, guys, give us some credit -- but this still feels like one satisfying final salute.
