I've watched a few episodes from time to time but not enough to find out about the accident per se.
I think ImRaj currently wouldn't work because Suraj has no feelings for Imli. I guess Imli probably just have infatuation for him maybe not true love? Suraj is very good looking and very powerful so maybe that's why she feels attracted to him. But he definitely has no real feelings for her yet. I think either 2 things will happen: 1) imli's love will change suraj or 2) he will do something so horrible that imli will be shocked out of his love.Till then, no imraj for me!
I think makers will pair up imli with chagan
