When I read the original scene for when the kiss happens (I sooo didn't know there was going to be a kiss btw) I felt like it would be the perfect scene for a kiss just by the way the scene read. Do ya get what I mean? Just by the dialogue and light hearted nature of it, you could
feel the proper way to end a scene or piece of dialogue like that would be a kiss.
And when I imgained that scene having a kiss, I had this image of them kissing and in the distance, maybe inside the building at a window, was H. Sort of watching over Eric as he exited the detention center. And of course being there to "watch over" Eric he would see the kiss.
I could imagine quirking his eyebrow and smirking a little before putting on his sungalsses and maybe turning and walking away from the window or just looking off passed them in the distance....as so many eps have ended
Either way, I definately think when H finds out he will be happy for them. Part of me thinks he has always known or seen the signs of these two....like everyone said he was perched up at the end of All In so he had to have seen their "moment." He will no doubt stand up for them and protect them and definately wish them well.....I think H is a romantic at heart
