I read a theory that sessions lacked their Knight's aspects. A2 lacked connections (blood), the kids sessions lacked time (early reckoning). But what did the A1 session lack, having a Knight of Mind?
The whole “session lacking their knight’s aspect” isn’t canon. The A1 session is proof of this since Mind is apparently supposed to mean logic but the A1 trolls did everything correctly, it was just a null session.
