GOTCHA! Trickster was a trickster after all - he was Helene's half-brother Luzi in disguise! Which means Fixban is ALSO a winner of the Guess What Happens Next contest! (Fixban, please let me know what you want me to draw!)
There have been a few mentions of Luzi throughout the comic. We even saw what he looked like at Helene's NYE party back in Ch9. And remember all those times Trickster got a weird look in his eyes? That was Luzi showing his influence. I've actually got a whole Google Slides on foreshadowing moments; let me know if that interests you guys and I can post it here.
I'll also share Luzi's Toyhouse profile when it's up on Thursday! (I schedule pages in advance, so I can't link it right now.)
I'm sure everyone is eager to hear Luzi's explanation too... hehehe....
UPDATE 7/11:
As promised, here's the Foreshadowing Moments slide deck, and here's Luzi's Toyhouse page!
