Dahlia release pre-patch thoughts

There are only few hours separating us from the new Star Rail patch with Dahlia. I really can't wait for it!
It seems like this is supposed to be the "real" ending of Penacony, even though I'm not really sure what they mean by that. Does it mean that what we saw in the last patch of the cycle was all fabricated by someone?
I quite like the last patch of Penacony with Sparkle and Firefly aboard the flying ship with the chase to find all the Sparkle bomb dolls and the fireworks at the end so it would be a bummer if it turns out it was all a fabricated lie.
