I guess the first time I started liking SR was when Sid grabs ridz in the locker room,and tries to show her what molesting actually is, and when tears comes in her eyes and seeing that sid leaves her and go away. The way her tears affected him, I think that's what got me first hooked to the show. I know it wasn't a romantic scene but it's after that scene that I was like OMG I have to see this both madly in love with each other. And I got SRified.
But the scene which made me completely and madly fall in love with them and more importantly made me JeRanified was the hug scene that you have mentioned . It was just so magical and instantenous and beautiful and sizzling.... Oh I can go on and on!!! :P
ps: nice post!!!
