Dakh was selected to part of the Wraithfall. He was saved by John Sheppard and brought to Atlantis. When walking around with Radek Zelenka, he took the opportunity and smacked him. He then waited until the wormhole was opened and he escaped. He ended up back home and was picked up by Wraiths. He was drained by them, but Sheppard once again saved him just before dying. Back at Atlantis, Dakh wanted to speak with Sheppard before dying. He told him that he understands that he only wanted to help, but he doesn’t forgive him because by helping he put his entire homeworld in danger.
