[Boone does miss home, and his first thoughts on hearing about the quarantine were that he could finally go back and see everyone again. He could take his cat, he knows it doesn't mind eating meat and there's plenty of it back home. He's sure everyone would be interested in the beast because they've never seen one before. They no doubt missed Rex, too. Especially Elle.

So when Niko knocks on the door, his thoughts are mostly of home. He's packed a few things away, but not much. He's been helping out with the skeleton problem, wearing the armour he found inside that temple. When he answers the door, his eyes immediately fall on the beast in his arm.]

Hey. Your cat got fat.
