(Maybe the character could act as a way for them to get blood and/or as an adopted child. It would be interesting to see Sam try to talk to the youth and get the youth to relate to him. It wouldn't be hard to guess the two would be vampire's anyway, seeing as humans are slaves (mostly for feeding sources or house servants) in this universe.)
Cameron was relieved when he saw Sam happy and excited, happily following his boyfriend up to the porch. He couldn't help but chuckle when Sam looked around for an key. "We don't have an extra key, love. We have a key for you and a key for me." Cam held up Sam's key for him that was on a cute key chain that Cam had recently bought for Sam. It had this cute little heart on it that had ridges on the side of it where Cameron's own heart could fit in the ridges of it. The key chain was mostly a cute couple thing. "I'll let you do the honors and open the door to our new home."
