Baker's Dozen 2 - Sidekick

The second of my 13 Ace Attorney fanart prompts I'm doing this year as an abbreviated Inktober. This theme is Sidekick, and I chose Luke Triton!

I particularly portrayed him during the time when he was being--minor spoiler follows--Phoenix's sidekick: lying low in the back streets of Labyrinthia. But as an adherent of the assertion that Ace Attorney and Professor Layton are one story, I'd probably accept any suitable Prof. Layton character for any of these prompts if you can make an argument for it.

Here is the prompt list: www.deviantart.com/firefiriel/…
