Patience
He had never considered himself a patient man.
He loved speed – racing cars was his dream growing up. He needed action – that's why he joined Time Force. Then they got the morphers and became Rangers and he got the thrill of the chase.
Then one day he looked up and lightning struck his heart. One of his friends had now become more to him. Katie, who considered herself the friend never the lover.
He tested the water a few times and she never appeared to notice. So he plotted and planned. Decided that those ideas wouldn't work. Did some more plotting. Then he just stopped. He was still attracted to her; sometimes he ached so badly for her that he couldn't breathe.
That's when he started to consider himself patient because he was waiting until she was ready to think of herself as more. His friends considered him cowardly, though they used harsher words.
Whatever it was he was willing to wait because she was worth it.
