My favorite Allen and Lenalee scene was the one where Lenalee comforts Allen, who felt awful about failing to save Suman, by telling him the he DID save Suman in her mind. This scene really warms my heart and is just too beautiful for words.
I think that scene was the 1 definitive scene where there was no doubt they love each other. More romantic you can't get. The way they were in their own little world staring into each other's eyes and the tenderness with which they spoke to each other, even down to the way she touches his face and hair.
I have never thought that touching someone's hair could be so erotic lol
I loved the part where they realized there were other people around them and they got jerked back into reality like "wha? where did you guys come from?" lol
