Storm Spark hasn't seen his father in an age. Things have changed since then, he's gotten married, had kids, and found out a lot of things about himself. What he doesn't expect is just how well Shimmer would get on with Forge. And it's not just jealousy that blossoms in his mind.
Not by a long shot.

But what can a stallion do, when he's just as into the oddness as his family is?

The answer is watch, and maybe have some fun too.
