Thank you, Centex. I wasn't entirely sure how Brandon having a little video fun with his husband would be received. Especially including two others, but your reaction is enough for me that it works.
People, lycan or otherwise, would only know about an Elemental if they decided to reveal themself. Ethan ended up being exposed, at least to those close to him, by his gifts manifesting from strong emotions. He had minimal control until he and Aiden figured what was triggering it. He also chose to makes himself known to help the Lycan Council.
