Is Bobby Strong or Weak?

In my opinion I think Bobby is kind of in the middle of being strong or weak because he is strong with understanding and being invisible but that's it. He is weak with talking to Alicia and making choices and doing what he wants. He is kind of strong in the inside but not really because he is strong about some things but weak about some things. For example he is weak and strong when his parents got in a car wreck but he is a little bit more strong than weak.

All of my group members agreed with me that Bobby is in the middle of being strong and weak. Because we all agree that he is strong about being invisible but he is weak with Alicia and doing things with his invisibility. Like he never does anything out in public or he is scared to get caught. He also is in the middle of strong and weak in the inside. Like i said before with the car wreck and all if this stuff with family and invisibility.
