Jack found himself and his three companions coughing on the other side of the event horizon. As Sam had predicted, it only took them a moment to stop their coughing fits and grow used to the soggy air. It was incredibly loud due to the ferocious winds and Jack had to yell to be heard over them. Teal'c took point and Sam led them toward the cloud, steering the F.R.E.D. unit and watching it's internal map-computer all the way.
"Wow…" Jack said staring up at the billowing wall of purple cloud before them. "Is this it Carter?" he shouted. She wasn't loud enough to reply, so she gave him a thumbs up and pointed to her watch, telling him that it would take some time. He and Daniel, (Teal'c stayed behind to keep an eye on Sam), moved toward a small dip in the ground that looked very much like a foxhole and settled into it where the wind wasn't tossing them about.
"I really don't see why I had to come," Daniel said, now audible without the wind. "I'm a linguist, not a scientist. I can't help at all on any planets without people or at least ruins on them."
"You were offered a desk job when we first got into this…" Daniel didn't reply. "Besides it's been a blast right?" Both Jack and Daniel smiled and the latter nodded in agreement. It seemed like quite a bit more than four hours before Sam called them out of the foxhole and signaled that she had her samples.
It took a lot of wheezing and gasping, not to mention the two times that Jack had fallen in an attempt to pick Daniel back up from his constant tripping, but the team eventually made it to the gate with minimal injury. As Daniel moved forward cautiously to dial the gate, Jack thought how ridiculous his original feelings about the mission had been.
"O'Neill!" Teal'c shouted, pointing at the Colonel's shoulder. Jack had no time to react. He opened his mouth to shout and the mature Goa'uld symbiote flung itself into his mouth and dove through the back of his throat. It took a moment for Jack to realize what happened; the back of his throat hurt a lot, but when he reached up to massage it with his hand, he found that he couldn't move.
"Colonel!"
"Jack!" The shouts issued from his friends' mouths were no longer muffled by the wind. He felt himself try to step forward and mad every attempt to resist, but he was helpless to stop himself. Jack had to watch powerlessly as the Goa'uld hit Teal'c, Daniel, and Sam once each with the zat he carried, a prisoner in his own body. He was forced to walk toward the DHD and began to put in an address. His futile attempts to resist were making his mind weak and as he walked through the event horizon, he blacked out.
