"The one pic we got of them in the same frame can't be sourced, and that's for a reason. It was intentional and the release was controlled."
Well it can also be that the photo was without source because it was prohibited to take photos in that zone - that´s why we don´t have any more photos from that area than just this one and the other one with Louis and that girl...and that´s why I believe that receipt because they knew they were safe and there won´t be any evidence of them - and so that person who broke this rule didn´t want to get into troubles so they send it to HLD and said "but post it anonymously". I don´t want to argue, it´s just thinking about other possible theories. Or it´s as you wrote, someone from their team took it and shared it for this reason to show HL were in the same room after ages.
On the other hand, it was us larries who were clowning that H will be there too and when this photo came it was 50/50 if it´s H or literally anyone until we found out H was actually there as well and what he´s wearing. This photo is not on harries AU and (because they also hate Louis) harries have no idea their favourite was there with his "mortal enemy" and they were spotted in the same room and now they must be furious and backbending to come up with their theories when reading those hilarious news how H joined Louis for Euros and they catched up somewhere off cameras lol.
I´m just thinking if you have some theory why H is turned back? He´s standing close to Louis and Ed so I think they were all talking together but maybe when this photo was about to be taken with words "Act natural"//he was aware that someone is about to take photo because H has his superpower to always spot camera, he quickly turned away to not make it that obvious because the only purpose of the photo is to show HL were in the same room, not that they were there together and gossipin´ with Ed.
P.S.: Love how both HL are still mia since Sunday and sure H will pop up somewhere when Louis will be in Spain maybe just today, he´s performing tomorrow.
I don't think photos were prohibited there. It's just respectful to not post pics to social media, if people are there who don't want to be seen or placed there. It's a VIP area and VIPs knows how to behave. They want privacy, they give other people privacy.
I think the pic was staged and that's why Harry's back is turned. They wanted to show they were in the same room, but not make it too obvious. Start small.
I think H was spotted in Scotland golfing on monday, but he's been mia since.
