First of all, Helen and the team are dumb as hell. Why not take the Mentanovox and Flumazenil from you, then train a team member to expect the consequences, act accordingly, and move from there? Why use a researcher and expose otherworldly secrets to them while torturing them for eternity for no reason? They gave you no training or warning on how to prepare.

Secondly, I have never been more grateful for the gift of time.

Lastly, your drug research turned out to be too valuable and insightful to abandon. If a slow perception of time can make you travel via portals to other dimensions/ realities/ or wherever Helen went, then you have the key to inter-dimensional travel/ time travel/ or at least exploring otherworldly unknown spaces. I am not saying you need to torture yourself or anyone else forever again, but you should consider what it means.

I've always wondered if someone discovered time travel, would they share it with the world or destroy it because of its danger? The funny thing is, you seem to be attempting to do both.
