Bruised. Beaten. Stabbed. Sapped of energy. Tricked. Mentally played and abused. Perhaps you've even seen your home world destroyed, depending on how Homestuck you are. Any way you slice it, characters go through a lot of crap.
There's nothing wrong with wanting to see them get pampered and taken care of when they're ailing. In canon, they may not have someone who can provide them with care when they're injured, support and love when they're sick, and physical intimacy all around. In this post, AU or other scenarios can provide them with a caretaking partner of their very own (or, maybe, someone to take care of, if the reverse is their preference). So, for once, weary traveler, you don't have to carry that weight all by yourself.
