I think Jorn would want to avoid any touchy-touchy with anyone at the moment until he has solid proof that the others will be 100% healthy if he does touch them. So you can expect he's gonna act like a pariah/leper. After all, he's still pretty scarred mentally and emotionally after nearly having his girlfriend explode in a fountain of pus and gore as well as the dozens of anonymous npcs that he may or may not have come in contact with warded in sick bays across an imaginary cities and towns.
