1. Did Erin respond to the comment about "the ritual" from the last panel of the previous comic? That would imply that the speaker is bleeding over from one scene to another.
Mention of the ritual is in the last scene in the possibleKanti thread, which is actually the last page but one. It's possible there's simply a discontinuity in the Erin thread - after all Erin has changed position and become naked since the last scene. But all their heads are in The Cloud; there may be some crosstalk. And all of these scenes of seduction presumably share a common purpose, so it wouldn't be too surprising if it turned out to be the same ritual.
