My Sister's Protector

ie. Shining Armor. Shining Armor is his sister's protector.

I thought of something recently. We all know Twilight’s cutie mark is formed of several white stars around a pink one and Shining Armor also has a similar pink star over a shield as his cutie mark. Could he have gotten his the day he swore never to let his sister come to harm?

This would also retroactively explain my non-canonical thing where Shining Armor is wary of that orange pony Twilight hangs out with.
