- Patrick Stewart as Gurney Halleck when he recognized Paul Atreides amongst the Fremen that were raiding the smugglers' spice operation. (from David Lynch's Dune)
- Jeri Ryan as Seven of Nine delivering the line, "You're hurting me," to the advanced drone as he sacrifices himself for the good of Voyager's crew. (from Star Trek: Voyager, "Drone")
- The silent and subtle exchange between Amber Benson and Alyson Hannigan as Tara and Willow just after the memory crystal is crushed. (from Buffy the Vampire Slayer, "Tabula Rasa")
There are probably more, but I'm curious to see what you all will come up with. Thoughts?
