Evan halted for a while as he thought on the answer. If without it this potion wouldn't work without a tear... then, he had to make a decision. He was either going to waste one more tear for such a stupid potion, or he would simply leave. Although staying would be better for his well-being, he just didn't want to waste phoenix tear on his behalf. It wasn't hard to guess the correct choice here. His heart started to beat faster with the decision he made: he'd leave, as he'd agreed to do before. Cleaning his working area, he returned the unused stuff and "Evanesco!"ed his half-potion. Then, packing his stuff, he simply and calmly said "I don't want to waste that tear, then," to the professor and walked through the open-door. The consequences he didn't want to think about, but he felt quite nice, actually, although his knees were shaky a little with the fear of Lafay.

As he got out of the door, it dawned on him that with this rather rebellious action he could get a detention. Oh well. There were more important things than detention, and if he got lucky, he could always study the potion from books.
