1. He's a great character. He's a genius, he's shy in all the right places, he knows when to be serious and when to topple in a pile with his teammates.
2. Did I mention he's a bit shy? And he tends to let people walk all over him.
3. Trip runs into one of his own kind on Earth, and he can't figure out why.

4. The ability to instantly understand and repair any machine.
