Jack was a witness to the whole upset. Actually, he was not fond of the "quarantine" proposition either, no matter how good this guy Carter made it to be. However, the situation at hand was a bit escalated, with Allen being a little too aggresive towards a pretty violent Sky...or Jade, he wasn't sure what was with the name change either. He tried processing some ideas and come up with a good enough solution to ease the situation. Then he said:

"Mister Carter, I am Jack Spades. I am also a victim of Vitus' experiments and, with all due respect, the word "quarantine" doesn't go well with my current vocabulary. Although I can see the nescessity of us being examined, I would like to make a counter offer. Considering we spent most of our time in the ship together, it is safe to assume that if one of us had something infectious, then all of us would. So, I believe that we should be a little more mautre and rational and think that despite being superpowered escapees from an alien spaceship, we are still human and as you can see, there are people among us that are too young to experience lab testing. So, instead of possibly scarring Sky's-or Jade's-I quite missed that part, Al's and Rowan's mind with the image of more lab testing, how about you take me and Allen, or Dr. Willows if you prefer, to see whatever you want to see and let them go home? Of course, you will provide the children with a cellphone or another communication device, so if something happens, I can get to them immediately. Is that good enough?"

He also turned to Sky/Jade for a brief moment, adding with a warm smile:

"Is that ok for you, mademoiselle?"
