The Phoenix arrived in the brown dwarf system, the star rapidly destabilizing. A Tholian patrol passes by, forcing the ship to hide in the tail of a comet until the star began to go supernova. The Tholians fled the system, allowing the Phoenix a straight shot at the anomaly. Meanwhile, Ensign Lopez was thrown in the brig for insubordination.
Commander Vetrel, Lieutenant Winston, and Lieutenant Foster were put on a shuttle and left behind at the edge of the event horizon. Once they were clear, the ship dove in, using Cameron's warp field theory to try and get home.
Where are they now? With the transition heavily damaging the ship and knocking sensors offline, no one knows.
