10. Witness

Complete story — includes the ending

Cole and Cassie meet Athan in 1959, at the House of Cedar and Pine, and try to convince him he can choose his own destiny. Jones's forces appear, having been told the location and time by Olivia. Titan splinters in around the house. Jones shoots and apparently kills Athan, whose personal time machine splinters him away. Mallick takes Cole, Cassie, and Jones to meet Olivia, the Army's new leader. It is revealed Olivia and Mallick had conspired to manipulate the members of Project Splinter into finding and killing the Witness. Unexpectedly, Athan splinters in. A flashback reveals he had splintered to Jennifer in 2017. She had summoned medical help to save him, and he had spent a year helping her work with her visions before returning to 1959 to rescue Cole, Cassie, and Jones. The latter flee and return to 2046 while Athan confronts Olivia. He tells her she, not he, is the true Witness. Shocked, she kills him and gives orders that Titan be splintered to 2046 and the temporal facility destroyed. In 2015, Cole's father gives young Cole a cryptic note from Cole's mother.
