You and Allison are... friends? It's a little hard to be certain with how closed off she usually is. But you're at least certain that she doesn't outright hate you. You're both kinda weird, but that just means you've got more in common.

Tonight, you're both in your room, relaxing on your bed, when Allison suddenly breaks the silence, "Hey... you wanna see something cool?"

"Hm? Yeah sure."

Allison sits up, draping her legs over your lap before putting her hand down in her shirt, digging around before pulling a switchblade out of her bra, grinning at your mixed shocked, impressed and flustered expression.
