Quentin was raised by Clan Dundee, and considered his adopted sister, Clyde, to be as as a blood relative.

Although Quentin could learn things quickly when he put his mind to it, he often become frustrated by failure on his part, and was easily tempted to seek an easy solution to the problem, or use power for his own gain. But would usually do the right thing to do.

Quentin would fight with the MacLeod ancestral sword on occasions when Don Ramirez trusts him to use it, and also uses a boomerang.
