And look! It has grown wings! It must be close to maturing.
Young dragons are relatively defenseless. They are born with relatively soft scales, which are shed and replaced with harder ones as the hatchling matures. Once a hatchling’s wings grow in, it marks the beginning of maturation. At this point they are often capable of hunting on their own and are usually left alone by their mother.
Thomas initially is very flippant and seemingly arrogant to strangers. However, he has more of a sense of humor than most Celestials, similar to Molatoff's. He liked Molatoff from the very moment he met him. If one gets to know him, they'll find that Thomas is a deeper, more caring dragon than he wants to reveal.
One of Thomas' major traits is an overpowering loyalty to his family. He is willing to put his life on the line to save any one of them and has done so for Molatoff on more than one occasion before they had any sort of a relationship. In the case of others, he can be rather brutally blunt, such as describing Butterfrill as a coward and advising Molatoff that the nervous hatchling would only endanger him.
