Peridot appears surprised by this request... Probably because she has primarily been bossing people around out of a petty need to make herself feel empowered in a situation where she's actually quite powerless. Only a tiny bit of her motivation is coming from a desire to be genuinely helpful. Basically, for a second, it almost feels like Strange just walked up to her and requested for her to give him a wedgie or something.

She blinks at him, and then nods. "I can do that. These weird plants aren't really the ideal practice subjects, since I'm not intimately familiar with their genera, but I can show you the basics."

Just like that.
