Gold knocks up one of his groupies and freaks the hell out because he isn't "responsible" and he's way too young to be a father... so Silver and Lyra step in to help the young Champion with his new bundle of joy. Lyra/Gold/Silver as a committed polyamorous relationship develops because of it.

Bonus points: Lyra turns out to be very knowledgeable about raising children due to her experience with her grandparents (the daycare couple) and is all like "chill, I got this."

Super bonus points: Silver is the most "maternal" of the three and totally drops all the tsun and goes complete dere for the kid, but still treats Gold like shit.
