The golden trio when...
Hermione had found your Bowtruckle called Thomas wrapped up in your PJs. Dumbledore hadn't aloud magical creatures on the grounds unless it was for a lesson. A bowtruckle wasn't dangerous but it was small and can be quite. You sat at were you by yourself while your fellow Gryffindors made noise around you. They sat around you so no one could hear the conversation and you couldn't run away.
"Y/n, we know about the bowtruckle."
"What! Godric, I knew I should have kept him in my pocket. Wait you won't tell anyone, will you? Please don't, he's the only friend I've got."
"We won't tell but you need to keep an eye on him, Hermione nearly killed the poor thing."
"We promise we won't tell as long as you keep it safe and hidden."
"I promise."
