So, Whitley is basically described as being a miniature version of his Father in both appearance and personality, just like Artemis Fowl.

Also has an alcoholic mother who isolates herself, is rarely seen in her own home and is implied to be mentally ill, just like Artemis Fowl's mother Angelina Fowl.

Mocks Weiss as he watches her try to escape when she is more or less trapped in her own bedroom, much like how Artemis mocks Holly as he watches her try to escape the room she is imprisoned in at the Fowl Manor during the first book.

Also 90% of the plot of the Artemis Fowl series after the first book is Artemis making unlikely alliances with people he's wronged in the past so they can take down an evil disgraced scientist trying to ruin everything for everyone.

Now gee I wonder if we have a disgraced evil scientist anywhere around here?

Adding in Whitley being suspicious of him

This boy's definitely gonna try something down the line against Watts. Only concern is that he might overestimate himself and it's going to backfire like in Eternity Code (which also ended up with Butler temporarily dying and forcing him to ask Holly for help)

KLEIN NO

Also placing bets that while he's mainly motivated by wanting to live up to his Father's expectations of him, that he also has a soft spot for his Mother too. With the Kai/Snow Queen allusions Whitley and Willow have I'm thinking the first time we see Willow onscreen will be with Whitley.
