Thanks, this is quite an interesting scenario and I'd say it would be plausible in the AWAM world and style. The only "problem" as noted by
Sabertooth__ is that the museum will be closed in the evening and Jason and Haru promised a "free, private tour through the museum when nobody is there!". But other than that (there still could be surprises/changes, who knows) it is really something in the style of the game.
About the event, I wonder what will be the **theme** of the event. There is a possibility for the event being a sort of cross-over between the 3rd task and Sam's concert (from a **theme** point of view).
Obviously Art will have a major place in the event (as in the 3rd task), two art history students and at least Sophia who loves it. So one could expect that Art will be the catalyst of the event, something that can be used to bring the two couples closer in terms of interests and common passions. They are strangers after all as they met only once, so I'd expect that art is used to get them closer. And if the 3rd task is to take as reference, probably L&P has probably prepared (or will prepare) another lecture on art. Let's just hope Jason is not the secret son of Xavier and inherited his loquacity

(BTW, the name, Jason, is already a nod to the greek mythology, but I let
Apollodore do what he does best

)
The second theme is sport, as already mentioned in the first meeting in front of the museum, and again there is a possibility for a similar cliché as in Sam's concert, i.e. the charm of the quarterback and the nostalgia for the old times in school. From the dialogues it seems more Patricia the one involved in that path.
It will be interesting (IMO) if and how he will play along with these themes, how they will drive the event and, obviously, what will be the outcome. If it will be the atmosphere of the museum, the shared passion that will lead to whatever has to happen or in the end it will be something like an "accident" like the one you have described.
In terms of what really could happen, it's too early to call IMO. We still have a whole Friday to see how Sophia's corruption progresses (Aiden, side job, Sam, Dylan...) plus another 3/4 of Saturday for which we don't know squat if not the 1st side job. (he promised the list of events for PD 14 a while ago...). So it's really hard to tell what "realistically" could happen.
