Upon arrival in Andromeda, the ark is attacked by the kett. When the situation turns desperate, the ark's captain orders her to hide amongst the normal population in cryo, and dismantle her SAM, so she would remain safe. She is awoken by Pathfinder Ryder to repel the kett.
She leads landing party on Archon's warship, trying to save captured Salarians. She later assists Ryder during kett ambush, losing one of her crew-mates. After Ryder successfully obtains information about Meridian she is pinned down by overwhelming force of the Kett. Unable to save herself she contacts Ryder, saying her goodbyes as one Pathfinder to another.
If Ryder chose to save Raeka over the krogan scouts, she acknowledges her fellow Pathfinder's difficult decision.
