Welcome back, Player. I've given it a lot of thought, and I believe that the Professor Hewahewa at Tiamat Stronghold is the same Hewahewa in future Dark Poeta.

Maybe if we kill him now, it will influence how future Dark Poeta turns out.

It's at least worth a try.

Player: Accept.

Welcome back. How did your encounter with Professor Hewahewa go?

Player: "I killed him."

Excellent work! It'll be a huge help to our forces to have him out of the way.

I don't know if it did anything to change the future of Dark Poeta though. If it had, I think our memories of Dark Poeta should have changed, but I still remember it as it was.

At least, I think I do. Paradoxes with time, space, and dimensions aren't really my specialty.
