The main problem with BARF is that you have to build a set for each memory, so that the projections have a physical anchor. I only demonstrated it with one of mine, because I could build the prototype set to the exact dimensions I needed. It was one of the rooms in my parents' old house; we still had the furniture in storage for me to drag out and measure.

So what I'm thinking is that if that's the most effective treatment for you - and I'm not saying it is - then I'll need to...shit, I don't know. [His mind flips through options and discards them all.] Some kind of VR would work best, but it still wouldn't give you the tactile feedback your brain needs to help you alter the memory and work through your trauma. And, frankly, I'm still not sure it would do what you want it to.

[The human brain is essentially an elaborate computer; Tony knows that. And the only way he can see to fix this is to rewrite the programming - but he'll be damned if he has any way to go about it. BARF might be a stepping stone, but it's not much of one.]

Don't worry about it. [Tony waves a hand at the suggestion of compensation.] It's something that needs to be done, okay? I can't just leave you like this.
