Episode five was a continuation of episode four.
The Ariana had suffered a breakdown of her temporal drive, resulting in them being trapped in 1912, with a temporal distortion wave heading towards them fast, they had to be out of that time before the temporal distortion wave hit.
Using the knowledge held within the now un-encrypted file, Savage led an away team to an abandon base, there they found and salavaged parts to repair TIA.
The reparis to the temporal drive required someone to go inside the core, an act that would kill any living being within minutes, but now with TIA back online, the TIA AI Hologram could enter the core and conduct the repairs without jeopodising a crew member.
With the temporal drive repaired and TIA in manual mode, Savage seized the opportunity to covertly try and send the Ariana back to their time, but did it work?
