Hi, I was wondering if in the following examples, "cuando" can be interchanged with "si", because there are lessons about si-sentences with the exact same combination of tenses/modes to excited hypothetical situations.
Ella te habría perdonado cuando tú le hubieras pedido perdón.
She would have forgiven you when you had apologised to her. (hypothetical situation)
Dijo que me llamaría cuando llegara al hotel.
He said he'd call me when he arrives at the hotel. (future/hypothetical event)
