That's what I was referring to as well: Buffy lying to Willow about being in heaven, and so forth. She's done it before.

And yes, it was uncomfortable then and I'm pretty sure it's supposed to be uncomfortable now. Like I said in my own review: Buffy and Willow can still fight together in perfect synchronisation; their differences haven't severed the basic bond between them. But it does mean that they can't face looking at each other for a while, and walk off far apart and not talking to each other at the end of the comic. (Which is another trope the TV show often used as the final scene to a sad episode; characters walking away from each other in silence. 'Harsh Light of Day', 'Selfless', 'Tabula Rasa' etc).
