Finding a location was not the hardest thing, something of an old pair of what might have been two side by side stores that was was momentarily boarded up.
Leatherhead was distinctly not very comfortable with the arrangement. It was not his lair after all, but... It was a corner opposit the labs respectable public relations friendly looking neat lab front and one of the building was a story equal to the lab so they had a great view. And Leatherhead knew from his earlier explorations of the network beneath the lab it was a great place to operate from. As long a those that where mutants stayed mostly out of sight.
He was not expecting any one yet, he was now just composing a text message to Leonardo describing the place, location and the best way of entry to this boarded up sealed building which was through the first floor alley facing window and very small balcony.
Leatherhead had not done much in the way of cleaning. Mostly thanks to only jut having found the place and then realizing the way light from outside flooded in made a great basking patch. But he had found tables he placed together and discovered the power box, not a big challenge for a mutant like himself. And sending Leo the message and then one to Slash he resumes the basking. His great jaws even opening wide relaxed and enjoying the moment.
One other thing he had done was retrieve the brain thing, it was now in a larger aquarium like tank on what might have been a floating bench. It had water and some Cheetos to munch and was out of the direct sun.
