In the last episode (the two-hour premire), in the scene where Mal and Zoe try to pay off the old lady out in the boonies, Jayne sneaks up om a sniper, takes him out, then uses the rifle to support Mal and Zoe when the exchange turns into a shoot-out...what kind of gun was the sniper rifle Jane appropriated? It looked like some kind of .50 cal...
Other good parts of the episode:
The opening battle scene from the Revolt (LOVE the G-36's!)...
Mal, Zoe, and Jayne discussing the terrain and tactics before the above pay-off scene...
The incredibly non-PC Jayne at the dinner table (who else on TV casually discusses masterbation and Gynocologists?)...
The dinner table scene: Book asks if anybody objects to him saying Grace; Mal says: "Only if you say it out loud"...remember, during the Revolt scene six years before, Mal kisses his Cross before he goes into battle...
The Federal Agent holding Kaylee as a human sheild; Mal walks in on the scene and without hesitation pulls out his gun and blows him away...
Too much good stuff!
