They can't see me!

While Jason was curious about the Drake family's patriarch's strength and if he was stronger than Shane, the Flers seemed unaffected by the news of his appearance. They were occupied with searching for the necessary ingredients in order to concoct the evolution solution.

Furthermore, he also wanted to know how strong the group following the patriarch was, however, that wouldn't mean that Jason wanted to rush mindlessly towards Old Drake in order to satiate his curiosity.

There were too many uncertain factors he had to calculate and in the end, it was useless to figure it out.

What would he gain by knowing who amongst Shane and the Drake family's patriarch was stronger? 

Shane was not around and was seriously injured. Currently, there was no way for him to do anything if something were to happen.

As such, Jason decided to mind his own business.
