>>2306552>>2306553(spoilers for professor layton & the unwound future)
That's actually Clive, one of the villains, who claims to be Luke (layton's sidekick) from the future. In reality he wants revenge because when layton's bros attempted to make a time machine ten years prior, it exploded and destroyed an apartment building that Clive's parents were in.
so basically someone ships them because they both lost their parents I guess even though Clive is comically evil
