Hey watch it, you can't just throw around pet names like that, that's Sinclair's thing.

Sinclair attempts to keep up for all of about thirty seconds before a wrong step sends pain shooting up his thigh and he stops for a moment to push his hand over the wound that keeps breaking open again. He sighs in exasperation and continues to walk behind Jack but it's not worth it to try and go any faster than he is.

At least Jack is in a good mood, even if it's just the ADAM talking. Even if something about it just rubs Sinclair the wrong way. The high'll wear off soon enough, they just need to get upstairs. One thing at a time.
