On this extract from Deathly Hallows part 1´s script, there is more action between the characters for the horcrux´s effect and RON/HERMIONE moment which we didn´t see.
An epic flyover. Three small figures move slowly below.
One figure — Ron — trails the other two: Harry and
Hermione. We CUT DOWN TO ground level. TO Ron. He
