The mare would have killed the two Crusaders if not for the hidden unicorn mare. Sweetie aimed her pistol to her barrel but didn't fire immediately. Instead she moved a lot more to the right and fired right into her forehead. A loud bang resonated from the pistol and hit the unicorn's horn. The horn, being the most sensitive and fragile member to a unicorn, got blasted away from its bearer. Effectively, making the unicorn mare faint.
However, what was on the horn was interesting. Upon a closer look, she saw an important detail. It had a golden ring on it. Sweetie put down her pistol for moment then looked at the unicorn outside. More specifically, the thing on his horn was another gold ring. That confirms it, the two unicorns both inside and outside the mini-store, are a couple.
She could see the tears streaking from his eyes as he held the SMG in his magical grip.
"Don't shoot! I- I'll surrender. Just please, don't shoot"

"It could be a trap. He's still holding that SMG of his" Apple Bloom said.
"Did you see his face? It looks like the face of desperation" Sweetie Belle countered.
"It still looks like a trap to me. I say we shoot him" Scootaloo was unconvinced.
Scootaloo could shoot at the unicorn outside with the pistol she's wielding or the trio could trust the unicorn. Unknown to the ponies both inside and outside the mini-store, an aura lingers in the air. It's crimson mist swirling just above the building. The Crusaders...
...trust the unicorn.
...shoot him dead.
