Donna placed her hand on the gadget of Jack's wrist. Within seconds, she was stood in the TARDIS. 

"Wow..." Donna said, her head going fuzzy. "Are...are we in the TARDIS?" 

But there was no time to ask questions. Once Jack and the Doctor had finished their momentary chat, the Doctor seemed to quickly go downhill. Jack and Donna dragged him to the med-bay, giving him a bucket, to which he instantly began to empty his stomach contents into. 

"If your this ill, why were you even doing exploring planets?" Jack asked. 

"Because he's a stupid bloke, just like any other man." Donna commented, trying to keep a light mood above the Doctor's bad condition. When Jack told Donna he was happy to see her again, she rushed forward and gave him a hug. 

"I'm more than happy to see you Jack, I had no idea how I was meant to get out of that place with the Doctor. If you hadn't shown up, we probably wouldn't have made it out." Donna admitted to the Time-Agent. "Do you know how to help him?"
