Did he look that visibly overwhelmed? Probably because he felt it.. Discussing things and pictures was one thing.. Brewing a full on potion like this...All the instructions at once.. Oliver was trying to focus on the first step first but it felt... Foreign. But he was thankful for Katy and the fact that she knew him enough to know he felt like a mess right now. "Thank you.." Really.. she was the best.

He took a deep breath and did his best to center himself. He was a little scared of making a mistake and looking stupid. But he remembered that making mistakes was okay. He needed to learn, even if that meant failing. "Aguamenti" He did his best to stop the water at the halfway point.. It might have been a little less than.. But nevertheless he made sure it got to a boil.

Now for the Juniper Berries.. The board just said the berries but didn't say how many. So he followed Katy's lead and put them all in cause he assumed that's what it meant and that she knew what she was doing here. Gloves seemed like a waste of time when it came to cutting the shrivelfig. So he just went ahead and cut that in half, squeezing out the juice and looking between Katy's and his. "Does that look purple to you?"
