I definitely love Porter as a character! I love that you've added his backstory in, since so many people (me included sometimes!) forget to give supporting roles back stories. The only thing I would suggest is that a few lines in you start calling him "Port", if it's a nickname I would maybe suggest having another character refer to him as Port beforehand so that the reader knows it's a nickname and not a typo :) other than that, I really liked this chapter!!
