Fancy Crane: Luis, I am so impressed. You two won the blue ribbon for the tango. I had no idea Aunt Sheridan was such a good dancer.
Luis Lopez-Fitzgerald: Yeah, she wasn't. I taught her.
This statement contradicts earlier episodes. One of Luis and Sheridan's first major interactions was Pilar's birthday party in the summer of 1999, where the two danced the tango together. Both were extraordinarily good, and Sheridan required no teaching whatsoever from Luis. The two had frequently tangoed over the years, but Sheridan had learned to tango long before she ever met him.

Julian Crane: You know, I hated your grandfather so much, it blinded me from realizing he was so right about the world. He said that nice guys finish last, and he was right. Because if you want something, you take it -- no matter who you have to step on to get it.
