Louis forgot his lines for the first time ever

So, I was watching the video to the gif that I just re-blogged of Harry pretending to spank Louis on stage in Cardiff (shortly before Louis forgot his vocals) and you can see that prior to that Harry points to Louis and then Louis walks toward him. So I looked for more footage, and I found another video, and while you cannot see all of it, you can actually see that after Harry pointed to him, Louis pouted as he walked towards him before Harry pretended to spank him. At least that is what it looks like anyway in the VERY brief moment on video. (Credit to Monika Rozynek for the video.)
