Leo,
In this thread we were talking about a "Feature Class" and not a feature. The concept would be completely different for the two.
Yes, while Reconcile/Post we can manually look at the conflicts and decide in favor of the Parent version, but for that to happen the feature should have been modified in both the versions....or else it will simply overwrite depending on what you chose(edits in favor of Child\Parent).
As for the other question, YES...it will remain in the replica geodatabase untill you synchronize.
Regards,
