That evening, Strange entered the school infirmary. Schiller handed him the freshly brewed Invisibility Potion, which gave off a faint green glow, and said, "Don't tell me I'm supposed to drink this during the actual shoot. This stuff reeks of fish..."
"Are you stupid?" Strange looked at him and said, "If you drink the potion and turn invisible, how is the camera supposed to film you?"
Schiller slapped his forehead and sat down on the sofa in the office's reception area. "Forgive me. I've been so busy lately that I'm a little out of it."
"This potion is just for a shot. They'll probably give you juice, then have a mage cast a spell to make you translucent, or just add the effect in post-production."
Schiller nodded and handed him the potion. "How are the Batmen progressing with their studies?"
"I have to admit, they're geniuses. Especially in Magical Botany and other hands-on classes—they learn incredibly fast and can draw inferences from a single example." Strange's expression finally improved slightly. "Most of them have also shown interest in the introductory class on magical defense networks. The plan is going very smoothly."
"What about that evil Batman? Has he been up to anything lately?"
"He really is quite evil," Strange said. "Earlier, you probably treated a student who injured his eyes by getting potion in them."
"Was that his doing?"
"More or less. But that kid wasn't innocent either. He helped insult Mercury Academy before."
"He really holds a grudge."
"All right, I'm taking the potion. The illustrators still need to draw it for the field guide. The director said they've already put the newly finished plant and creature field guides in the library. Go take a look if you have time."
Strange left the school infirmary carrying the Invisibility Potion.
