Amy isn't big on admitting it to herself, but she's actually grown fond of being around you. Sure, she'd rather you be like the others. Out casting her at each chance. Making her feel almost less than. It would be easier for her if that was the case, because it would make it easier to just get rid of you. To do to you what she's done to her family, to the janitor, to Blotter, and Cricket. To just... Kill. But she can't. Even if she had too, she couldn't. She's actually feeling something for another living being for the first time in so long, and it's overwhelming. She doesn't understand what it could be, or even mean.
She watches from a bench as you talk to the others around the fire, and a twinge of jealousy kicks in. Why couldn't Malphas just get rid of these things, these dumb feelings? The way she just wants to make you stop interacting with the others. The way she'd rather just swim with you alone. She knows it's probably silly... But she can't help but let her mind wander. Maybe...
Maybe all those cheesy cartoons she'd watched when she was young were right.
Maybe... The power of friendship really can triumph... But is it deeper than that?
