IDK there was something about roses too, like I think he gave Vanessa a flower and then later threw flowers at people to distract them so NPH could escape? I think that's what happened but idk, w/e.
Then two pics at the party:
From Jai Rodriguez's twitter:
From some random HSM fan kid person named Zach I guess:
And a picture of him leaving with Vanessa in which he is barely visible is here.
