The potions honestly sound pretty useful, and Ianto makes a mental note to look into this shop that Jim has mentioned. He'll have to ask for more details about them, how it works, what exactly bounces off of a person -- whether it's projectiles and the sort or whether it might have helped keep John from being stabbed for instance as well. He'll just have to find this Rosalind and ask, he supposes.

He turns to John at the question, before nodding. "Yeah," he replies. Careful about his response because while John has learned about Torchwood -- the hard way, through Ianto's memories themselves -- Jim still thinks that he's some regular office drone. God knows what he wonders about him getting himself caught up in all of this mess. "I know it's going rather above and beyond as far as our escort duties are concerned, but I can't just turn away from it now. Not if there's something I can do to help."

Even if that help is just to be there as someone to bounce ideas off of for John. He'd take it. Anything to feel like he were making a difference in some way.
