Plot Progression

1. Darol Awakens — The UDF approaches Darol after its year of dormancy. Its sudden vegetation attack kills Rita and begins the central time-loop crisis.

3. The Second Looped Soldier — Rita discovers Keiji and learns that he shares the same temporal imprisonment. Together they develop a theory involving a time-manipulating alien.
4. The Assimilation Warning — Killing the suspected alien fails to end the loop. Shasta explains that Darol is assimilating Rita and Keiji, leaving them very few chances.
5. The Core and the Cost — Rita and Keiji climb Darol and reach its core. Keiji offers himself as a sacrifice, but Rita kills Darol and breaks the loop.
