Q's changing levels of self image and self confidence

In both stories, The Dinosaurs and The Aquatic Uncle, Q displays two different types of of views for himself. In "The Dinosaurs", Q has a pretty good level of self esteem. He seems to view himself as very strong and powerful even though he fears being exposed to the New Ones as a dinosaur. However, in "The Aquatic Uncle", Q seems to have a much lower image of himself. He is constantly feeling embarrassed or thinks that somebody is tying to make fun of him. He doesn’t feel strong or powerful, in fact he seems to be the complete opposite. For example, in "The Dinosaurs", Q thinks to himself:

" The terror of the Dinosaurs still continued in the New Ones...at a spring a New One,

a young female, was drinking...I should tear her limb from limb."

This quote shows that Q knows he is  has the strength and ability to kill this New
One drinking at the fountain. He debates with himself weather or not to attack her in order to bring authority back to the dinosaurs. He knows that he is capable of this because he is much bigger than these creatures. Also, when Zahn wanted to fight Q, he had no problem standing up and taking him down. It barely took him a second to debate if he should fight him or not. He seemed like he was already completely confident in himself that he would be able to win the fight with Zahn, and he did.

Whenever "the time had come for Lll to meet my family, I postponed it...

I suspected she was remaining silent in order to embarrass me later."

This quote from "The Aquatic Uncle" shows how Q is constantly feeling like someone is going to judge or make fun of him when really, he's just jumping to conclusions. He was terribly embarrassed by the fact that his uncle N'ba N'ga still lived in the water while most creatures of his kind adapted to living on land. He was ashamed of his family and didn't want to introduce his fiance to his uncle even though he had no idea of what her reaction would be. Also, after Uncle N'ba N'ga and Lll met and Lll told Q that she enjoyed the visit, he thought that he was joking and was making fun of him. He was completely shocked when she asked to visit N'ba N'ga again and thought that she was just trying to tease him. In these two stories Q portrays himself in to completely different ways.
