I got further teary when Wash's dino scene came up.

I recently started watching Firefly again as well. I find myself getting all emotional at the oddest places. (The last time I watched Serenity I got all choked up, not at the part where Wash dies, but in the very next scene when everyone's piling out of the ship -- where Jayne looks up and we get a brief view of the cockpit from underneath. Something about seeing where they'd left Wash from that angle just got to me.) *sniff*
