#TBT. Behind-the-scenes photos of Aaron filming the Chief’s dream sequence from the BATTLESTAR GALACTICA episode 2×19: Lay Down Your Burdens (Part 1).

For weeks, Tyrol has been having the recurring dream that he walks onto the upper level of the hangar deck, climbs over the railing and commits suicide himself by jumping to his death. Cavil says it is because Tyrol has a subconscious desire to kill himself. Tyrol explains that he has had the gnawing worry since Sharon Valerii died that he might himself be a Cylon. Sharon Valerii never really knew she was a Cylon, even up to the point that she died, but reported strange fears that something bad was going to happen and she had to stop herself: how would Tyrol, or anyone else, really know if they were a Cylon sleeper agent or not? Tyrol is frightened by the prospect. — Battlestar Wiki
