There was a halt in John actually. Something that wasn't very common. She wasn't serious, right? There were plenty of trees he had met, but a deadly one? That was not so accurate. Also, there shouldn't have been a surprise that this woman hadn't a clue about yoga, she didn't look like she was from Earth- of course was a fine line too.

John dug through his knowledge of yoga stances and picked it out. Taking up his right leg he bent it and placed his right foot flat on the inside of his left thigh. "Make sure you're standing tall," Commented and then balanced himself while placing his hands together above his head with a slight bend at his elbows.
