What's the likelihood of Lux appearing in the next season of Arcane?

I've more excited about this with all the hints dropping that Lux may be coming soon to Arcane. Mel has voice lines for Lux, Katarina (Garen's love interest) and Ezreal (Lux's love interest) are confirmed characters.

I want to say that I think Lux's story will revolve around her discovering Galio and learning how to control her powers, and I feel like she might meet Jinx considering how often they're paired as unlikely friends in cinematics and skinlines.
