When is it smart to push Manny too far?

The short answer is never.

Kessler wants to test new combat suits - but also wants to try and find a 'safe' place to test out the expensive R&D.

Is there any place inside the ZOO they can find safe enough to test the equipment and get back out alive?

Peppy and Gunnar are helping but Peppy might have a reason to be a bit worried. 

The ZOO finds horribly new and dangerous ways to attack Ava and the team. Can Ava, Manny and the others adapt as fast to stay alive?
