"That's the goal, and you know it, but we've told you, Blaise. She can't be on potions this powerful for any sort of long-term period. We're already worried enough about what sort of memory or cognitive damage she might have from the fever and inflammation in her brain. Some of the ingredients I'm having to use, particularly in this version of the potion, are highly addictive. Finding something that lasts a full twelve hours is our first priority. Then it's about finding non-addictive or, at the minimum, less addictive, ingredients that will have the same effect. Theo was calm, despite having had to explain this same concept to Blaise, Harry and Ron several times over the last few days. "This batch seems to be the best in terms of effectiveness and longevity so it'll serve as the base for the next round. I won't keep her on this one for more than a couple of days, the amount of poppy latex alone is enough to make me reconsider giving it to her again at all. I'll spend the next couple of days looking for a suitable alternative and, once we have a working potion that won't lead to a terrible addiction or a shut down of her entire central nervous system, we'll start her on a regular cycle. It's not an easy process, and not a situation where we can throw shit in a cauldron and hope for the best."
