Yay! Harry is quite the champion, in several senses. And yes, I think that the moment the Albus that existed in Scorpius's head was overwritten by the real experience must have been fabulously overwhelming; one of those kisses where there is always a part of your brain that is happily shrieking "This is really happening! I can't believe it! Huzzah and let ring the bells!!!"

I do so hope it's not just my brain that does that ...
