The mid-season finale of Syfy's "Battlestar Galactica" prequel "Caprica" ends with the appropriately titled "End of the Line."

When Daniel Graystone (Eric Stoltz) finally sets a deadline for resetting the U-87 Cylon -- and unknowingly ending Zoe-A's (Alessandra Torresani) existence as she knows it, she makes a desperate attempt to save herself.

But when Zoe-A's plan backfires, she finds herself out of options, and out of time.

Furious with a recent comeuppance, Barnabas (James Marsters) ignites his feud with Clarice (Polly Walker) into an all-out war. Trapped in the middle is Lacy (Magda Apanowicz), who is forced to make a decision she may regret forever.

Daniel makes a confession to an already reeling Amanda Graystone (Paula Malcomson) that sends her over the edge.

All of that is coming in the mid-season finale of "Caprica," which airs Friday at 9 p.m. ET on Syfy.
