Bob felt depressed, their current situation was too much for his kind heart to take. He hated seeing everyone suffer, he hated being forced to run away, but what he hated the most was that deep down he knew Luke was right.
There wasn't much he could do to help, he wasn't a healer and he wasn't as strong as people thought. He did have the power to break a rock with his fists, but raw power meant nothing when he was at a disadvantage, and unfortunately, he had faced many enemies that naturaly countered his skills.
The only thought that crossed his mind over and over was how different things would be if he was able to actually cast any magic. Although he looked like a warrior and he wasn't as smart as his companions, he was actually pretty good at using magic, at least on role playing games.
