Now wAIT JUST A SECOND HERE---
First of all, there is no doubt in my mind that the dude in the striped shorts is harry. He's pale enough to be fetus harry and the hair is a dead giveaway.
But the other dude in the black shorts?? I'm pretty sure that's louis. I mean, I found this proof using KEY WORDS "Larry stylinson" and this came up.
It's kind of hard to tell, but I wouldn't be shocked if it was louis, especially after a picture like this one which could have been taken that same day...
I dont know. I know that the guys in this picture ^^^^ are more likely than not L and H, so who's not to say that the picture of harry and that other guy skinny dipping wasn't taken on the same say as the one of them kissing?:))
