Castiel hesitates a little - not because of Sam, but out of thought. He knows what to show him, but doesn't know if Sam might understand. If anyone might. Finally, he leads Sam down a path that looks positively unkempt compared to the rest, half-hidden behind low-hanging willow branches.

"They did very important work, then." Strange, that. And... intriguing. "That's a very central part of any clan. We employ Betas there, exclusively."

The path opens up to a small, wild pond, surrounding by a seemingly randomly mass of flowers and plants and grasses. It's not planned, like the rest of the gardens are. It looks positively... grown, not planted. There's a crooked bench nearby, and assortments of flowers that don't seem to match one another even remotely.
