Well Act IV of the event has been conquered, a nice little epilogue to finish everything off.
Spoilers for the whole event (Sunspray Summer Resort) and post quest dialogue.
Won't lie, wanted to grab the prize for ourselves after the events of Act III, but having Mualani give it to us isn't so bad. Recipes yay. Like how we took one last group photo, the Asha headband is really cute and Bennett did a thumbs up, oh yeah we're winning. Also Traveler I see you suggested to say "Lucky Star", they really can't deny that this event is about Bennett can they. The dinner was also nice, dude almost slept straight up in a chair again, just like in Shadows Amidst Snowstorms, and the interactions between Chasca and Mualani are such a treat.
Mavuika and Bennett did meet, off-screen (whyyyyy), and she did give some explanation to what was going on in Act III. Entering a simulation that the Abyss made of the Mare Jivari is something I can buy, still don't quite get what's up with the constellation. We could hope for some answers on that in the future, although this act would have been the better time to do it in my opinion. Oh well, nothing much to do about that. Props to Mavuika though for actually recognizing that Bennett may have wanted to go to Mondstadt, I swear it was like Mualani and Chasca weren't considering it. And to no one's surprise, yeah he picked to go back to Mondstadt, yay. Bennett talking about both of his sets of parents warms my heart, and that shine in his eyes, such joy.
Bit of a tangent here, but what the heck do they mean there's the possibility that Bennett's bad luck would come back once he leaves Natlan? Everything beforehand was pointing towards this change being permanent. It was claimed to be due to Bennett not being connected to the Ley Lines, which should be fixed after he came back. It shouldn't be hard at all to get permission to leave again from the Wayob and/or Mavuika, especially with the former being one of the few to acknowledge that Bennett may have wanted to go back to Mondstadt. Venti said the hardest part of Bennett's life was over in Act III, and the description of his skin even ends off with the hope that the Bennett continues to have this change of luck. I really only see them going back on this due to going back to the status quo, which would honestly suck with how nice the event was treating him the entire time. On the bright side it's only a possibility and Bennett is fine with the chance of it coming back (being used to it does have its benefits). And he brings up about how all the kindness from people more than make up for it, such a positive guy.
I guess we won't get an answer until he shows up again in something that has Sunspray Summer Resort as a prerequisite, so for now I suppose it's up to player interpretation. I may love pain, but I like to hope his loss of bad luck is permanent. He deserves it.
Anyway, the ending of this act was more so on the Mare Jivari and Istaroth lore that Venti gave us.
First off, Venti just casually said how Istaroth gave him some of her powers. And even with only some of it, HE was the one who got the Mare Jivari disconnected from the time line. That sort of power is honestly quite scary, and it's only a part of what Istaroth is capable of doing. I also think it speaks to just how badly the Abyssal corruption was at the Mare Jivari, because not only did the corruption mess with time and had the chance of spreading but it also much have still been in that condition after Sanhaj denoted the miniature Night Kingdom that contributed to it becoming mostly ash. Crazy stuff. He alluded to someone else knowing how the Mare Jivari actually disappeared 20 to 30 years ago (these people and their refusal to give an exact date), though I'm not too sure who it could be. I don't think it's Citlali since she is the one who first told us this information and she didn't know. It could be Enjou since we know he has a quest related to the region, though I don't know if Venti knows about him.
Oh also it's straight up confirmed that all the Asha we see around the area are actually the souls of people who died at the Mare Jivari that merged with Monetoo. Fun, not scary to think about at all.
Mavuika and Venti did actually work together, not only for the Bennett thing but also for the other souls that were trapped there, very sweet. Separating the Mare Jivari from the time line was the lesser evil, but I wouldn't blame Venti for still feeling guilty about its effects too.
There is also once again, another callback to the Of Ballads and Brews event during this exchange, where Venti says it wasn't the first time he brought memories to people. He did the same thing during that event and it also included Razor getting to see a memory of his parents as well (wow, Bennett and Razor are similar in that regard, both orphans who's parents were adventurers). And just like last time, it also tired him out.
Venti also does talk about people having the freedom to make their own fates as his wish, which ties in nicely with what Bennett said about being an adventurer and making his own fate in Act III. He really does care so much about everyone.
As far as I know, only Bennett, Venti, and Mavuika had new post quest dialogue, with the rest being the same optional dialogue after Act III.
We get to ask Bennett about what he thought about the trip and he even gets a bit emotional again with how nice everyone's been. Literally calls it "true happiness". He got a bunch of gifts for everyone, shows that he's interacted with Diona before, and is close enough to Draff to think of getting him a gift as well. He also apparently does, at minimum, know about Mona, finally crumbs on how he knows other Mondstadt characters.
Venti and Mavuika were together, planning to do a drinking competition. Eventually they end up talking about banquets, with Venti suggesting a joint one between Natlan and Mondstadt. Please, please, Mondstadt and Natlan are peak. I need these characters to interact again.
Something I completely forgot to say when I was talking about Act III is how Bennett's backstory connects to the whole idea of Natlan fighting against the Abyss. Its shown a lot as you go through the Natlan Archon quest just how much the fight against the Abyss affects their daily lives, and despite not being raised in Natlan, Bennett's life was still very much shaped by it. It was after all from an Abyss attack that he was orphaned and eventually ended up in Mondstadt. I just think it's nice that his character still ties into such a big part of Natlan even without living there.
Overall, I really liked this event, and I'm so glad that it's going to be permanent. Have some mixed feelings on the lack of some answers at the end, but it was overall a fun time. Plus, never going to complain about getting some more Mare Jivari lore. It just felt like a real love letter to Bennett as a character, and getting to finally know about his origins is great. May we hopefully see this man happy again in the future.
