The background of Colonel Sumner was the same than the main timeline's version until they reached Atlantis. Sumner made some recon inside the city. When Doctor Rodney McKay discovered that the city shield was on the verge to collapse, Doctor Elizabeth Weir ordered to fall back in the Stargate room. Sumner and his team were drowned (SGA: "Before I Sleep").
When the alternate Elizabeth Weir is awaken from stasis, she tells the Atlantis expedition the story of her own timeline expedition and Colonel Sumner's fate. When the team learn that Sumner drowned, they look surprised.
- All Sumner's appearance is a reuse of video footage from "Rising", Part 1, we don't see Sumner's drowning, we just hear him, then statics by radio.
