Isaac's eyes followed Zara as she walked up to the generator and crouched down.  It seemed she was atually going to take a crack at it.  The corners of his mouth pulled down and he nodded unconciously, quite impressed, then he followed Zara and crouched down beside her, taking a look himself but not saying anything.  Her monologue as she went through the available information was classic detective work, and she worked her way over to the wall.

"Do you guys ever build these things on hard surfaces? Or just toss the walls up on the dirt? They're coming in under the wall. See. Scraps of fur where it's been rubbing the bottom of the wall. There's claw marks from them digging under it. They are coming in this way, we'll need to go outside to this wall to see what direction they are heading." She spoke to Isaac now, pushing up to her feet properly.

It was a rare thing for Isaac Storm to be lost for words, but he it certainly seemed like this was one of those times as he opened his mouth to speak but... "Err..."  all he could do was nod a few times in agreement.  "Yeah... sure."

And with that, they made to leave the engine house, Isaac taking a moment in passing to tell the engineer smugly, "Didn't touch a thing."

Outside, as they rounded the shack, Isaac laid eyes on the nearby edge of town and found the likely spot where the mole rats were coming in.  It was a small gap in wall of burnt-out cars where some frayed chainlink fencing was supposed to be plugging up the gap, but was actually leaving a nice little rat-sized hole.  "There," he offered with pointed nod.  They went over.  "There's no way this isn't the place.  We should find tracks on the other side."

As they left town and got around to the point, Isaac started looking around.  He noticed a couple of things worthy of inspection, but one look at his accomplice told him that Zara was really into this, focused, maybe even enjoying herself, and so he let her take the lead again.  He too kinda enjoyed things like this.  Whether taking bounties on bad guys or tracking animals - it was all still hunting, at the end of the day.  Admittedly, Isaac preferred shooting people, something perhaps a little disturbing to the average person, but he still liked the little jobs.

With all this in mind, he decided against calling out how impressed he was with her tracking abilities so far and chose just to be in the moment with her.  "Anything?" he asked as he scanned the area.
