I have another idea.

We're about to leave the DDR camp here but I saw Ferdinand hurrying to approach us. He ran towards me and he gave back the containers which are cleaned properly and stacked together nicely. I was surprised to see it squeaky clean and almost all of us looked at him weirdly.

"What? Is there a problem sir?" he was confused.

"Nothing. Just keep doing what you're doing and we'd get along great. Thanks for cleaning them. I'll come back here in a bit since I would be installing something for better radio coverage. Remember I told you about the radio station at our place?" I replied and then we drove back home.

"Better not to tell them about our other friend yet." I thought to myself while my group acted like it was nothing.

"Okay sir, understood. Just drop by and install it to where it is needed." he replied.
