Varro was injured during the incursion into the ship, and patched up by Lt. Tamara Johansen. Though he appears loyal to the Alliance and its agenda, he is less hostile toward T.J. and the crew than other Lucian soldiers. He was instrumental in saving the crew's life after Kiva was killed, and was even briefly banished to a barren world when Dannic took charge.
Along with a handful of Alliance survivors, Varro is now living on board the Destiny and is functioning as the Alliance's de facto leader there. He and most of his people are cooperating with Colonel Young and Earth, doing their best to fit in with the crew.
