Past tense conditional
- could have
- should have
- would have
then there would be a past tense verb.
But what’s weird is that there would be a past tense verb (she whispers, “died”) that never happened.
Conjugation is such an odd thing. That there could even be a past tense for a non-occurrence. Future conditional is also an oddity. Conditional may just be a waste of thought. It is imperfect anyhoo.
