There are many possible scenarios indicated by the language that Dan has used to describe his relationship with HAL.

We know that many other coins asked Dan to review their code.
You suddenly want to make this case different.
I personally think he has at least some coding ability, and potentially lots, but we do know that he outsources a large amount of his coding.
No we don't know that.
What we know is that in making a coin they are all based on Bitcoin to large degree, so any smart person would get a third party to do the grunt work.
This is all that happened but for some reason you don't even have this very basic understanding of what actually happened...
