There’s a pine seedling in my Easter cactus

I think it’s most likely a shore pine / Pinus contorta, since I sowed a TON of those last fall. There were a bunch of duds, and the soil from those cells got dumped back into a bucket to reuse. Turns out, at least one of those seeds wasn’t a dud after all! He’ll join his other 4 dozen siblings outside in 3” seedling pots in the morning
