Remington is scary sometimes, but he has some real genuine moments like when he giggled at that kid at the start of this chapter. And he's been Rosette's guardian since before Magdalene apparently. There's a shot where it looked like he had fangs but I'm not sure if it was on purpose or not...
Oh and he's got a cool cross beam katana.
