I agree with what a number of people have said, this next update just seems like a waste of time and should've been skipped, like Dylan/Emma event.
The only thing I can think of is some how it brings Dylan and Ellie closer, so that she is more acceptable to Dylan and Sophia together. You figure that eventually Ellie has to find out about Dylan and Sophia, while Jules finds out about Sam and Sophia.
The shower scene we saw earlier in AWAM where Dylan spied and jerked, I presume Patricia saw Dylan and that come up at some point. So, I presume next update be tied into something but who the hell knows what the point of the next update will be, seems pointless and as some have already said, its not a party, its a small gathering off people.
