If Fred's boy needed him then he'd go. Even Archie knew that. All he'd have to say is that he needed his dad and the bodyguard would be right there. He wouldn't like leaving his Serpent, but he'd do it for his own kid. He watched Connor put the thermometer to Jughead's forehead and frowns slightly at the mention of the kid's temperature. Though, he does notice Connor watching him there for a moment too and he just gives the man a half smile. It probably didn't scream friendly, but he didn't care.
The moment that Connor pulls the blankets down though, Jughead curls up into a ball feeling the cold and tremors run through his body. There's a soft groan out of the Serpent prince and those eyes open a little, but barely. After all, the good doctor had taken away his heat source. One that he just wanted back. He's also got no clue who in the hell this guy was either.
"Dad?" It comes out as a bit of a groan from lack of use.
