I consider Issac being a part of Scott's pack because it's shown time and time again how loyal Issac is to Scott. He left after Allison's death because of heartbreak (and possibly a little angry/jealous of Scott because Allison told Scott with her last breath that she always loved him) but if he were to come back to Beacon Hills (Jeff you better make that happen) Scott would welcome him into the pack.
