Jenny Calendar

I’m sure this has been asked a million times but can someone logically explain why Jenny and Buffy are so mad at Giles about Eyghon? Specifically Jenny, who essentially cuts him out of her life for weeks after that.

Ignore the fact that we know at the time of the events that Jenny is actually lying to everyone. Let’s just stay true to the timeline up until that point.

Why are either of them mad that 20-something Rupert summoned a demon that has now decided to seek its retribution.

Is it because Giles wasn’t more upfront about what was going on? Should he have disclosed that a demon he summoned 20 years ago may come back to kill him. Even if he didn’t seem aware that this was even a possibility.

I have trouble understanding because it’s not like he didn’t this last week. It was many years ago and to me bars him from having to mention “Hey, I did this when I was younger just so you know.” to everyone meets.
