The patience that Remey had for the two getting in to talks about getting stronger then interrupting her alchemy was done. Ignus had already been watching her every move for a while now and that alone had been enough to get on her nerves.

Instead of potions, I might be able to condense it in to a pill. That would require an herbalist or a better alchemist but it's possible." Remey had already heard of the leech fish and she was ready to see what she could do.
