Clara places the tailsman so Boyd finds it Ep1 S1

I have been noticing that Clara has been up to no good just like the more obvious Sophia. A lot of people say Julie story walked to put the tailsman on the floor for Boyd so that the whole story can begin. But Clara is always the last person leaving. Or the first person entering- she’s always starting a hysteria. She’s easier to miss because she doesn’t have the shifty eyes. And we just assume she met the yellow man in season 4 I think she met him much longer ago.
