The sequence of events is as follows (IMO):
- The scene where they're having sex and Hutch calls (the bag might indicate that Vivian hasn’t seen Hutch since the morning).
- The scene where they’re getting dressed,
- The scene where they’re holding hands,
- The scene where Hutch and Viv enter the garden.
I also assumed that the garden party would be in 0.6, but after SC’s latest post, I now think it might actually appear as early as 0.4 (in my initial timeline, 0.4 ended just before the garden party).
In my opinion, SC didn’t say anything definitive — like who, what, when, or where

What’s more, I think he even mentioned that we’ll actually have to wait a bit longer for 0.6 than the previously expected September release...
