She had/appeared to have broken her arm.In English one is forced, for example, to distinguich an event entirely in the past from one that bears a relation to the time of speaking: 'She had ("have-PAST") broken her right arm' as opposed to 'She has'.
She broke her arm (exactly when will be supplied in/by the context).
She has/appears to have broken her arm (very recently/a moment ago).
She (definitely!) has broken her arm (quite recently i.e. at least "this" once...unless...this is the first item in a potentially long list of injuries sustained in the course of a lifetime? Again, further context will make it clearer).
Talking of The Grudge, what was your favorite scene? And how does it compare to the original Japanese version (Ju on)?
