I returned to homeroom, expecting the worst. At my previous school, I had made detention a habit, with frequent attendance leading to the multitude of teachers that oversaw this punishment knowing more about me than I would have preferred. On the bright side, at least I knew I could handle whatever was in store for me. I had experience on my side. I entered the room to find it empty, save Ms. Sheridan. She did not look pleased to see me. The feeling was mutual. I stated aloud "The Opequon Creek is a tributary of the Potomac River, and the Shenandoah Valley housed multiple campaigns between the Union and Confederacy often led by General Grant, the leader of the former." After that, I sat down and remained silent. Ms. Sheridan appeared perplexed now. She had expected the "new kid" to be rebellious and unintelligent, just another problem for her to resolve. In reality, she had just put me in a bad spot. We both sat in silence for a half-hour, neither of us enjoying our time, before she sent me home. I walked out the door to her classroom and immediately was met with a familiar face. Jubal. "She kept you here until I was ready," remarked the towering figure before me. "You need to come with me."

I like this a lot. You surprised me. Nobody bothered to research Ms. Sheridan's question or even consider why she is called "Sheridan" and why Jubal is called "Jubal". You got the hang of writing for "Choose your own Vybrainium Multiverse".
I enjoyed reading your story and was glad you did some homework, but I just noticed one thing that doesn't go with the flow. The main character was changed from "you" to "I". The "you" character was given to engage the reader as the one who chooses. I am considering getting rid of the "you" requirement but haven't decided yet.
