Not saying you're wrong about it being Dylan, but you are wrong about the t-shirt. It's a team and/or school shirt since all the boys on the soccer team were shown to be wearing it in earlier teasers. It could be any one of those ball-chasers, if we're going by their attire.L&P has already stated that Sam's part is only 9/10 renders.
The event is Dylan's
It says “M*m” in the title of the image.
In the image you can see that there are two people dressed in blue, which happens to be the same color as Dylan and Sophia's clothes (Sam has a brown t-shirt).
“Yeah, that must be Sam and Sophia...”

(Unless your point was that Sam is not a member of the soccer team, which I can't recall if that's the case. If this is true, then fair point to you.)
