Oh...so they were starting. Cool. Ella was a bit surprised by question because really, the title of the potion pretty much gave away what it was used for. She raised her hand anyway though, wanting to participate. "Professor, a Truth Serum is a potion that can get the truth out of whoever takes it..." Whether they liked it or not, yeah? Kind of dicey stuff, depending on who was using it and for what. Ella couldn't be that scared, though. She made it a point to tell the truth. Always had.
