The only mysterious female authority figures Tyl respects are not nice people, and would never say they care about other's suffering. So! He's not going to be convinced by the soft touch approach. He is 100% going to reject the offer, and be not in the least bit concerned about the horror movie ambiance that he starts hearing. Look, he's a mad scientist, sometimes this happens.

He is going to be interested in the people who start changing, though, and will be wanting to examine the changes, including taking samples to study. Maybe even under the guise of helping, though honestly, he just likes poking at cool stuff.

And if anyone starts growing parts they don't want? Come to him! Grineer are great at removing defective or unwanted bits of themselves, and Tyl's especially fashionable about it!
