What if you saved robb at the red wedding?, how would you play it out

Walder frey had men come into the twins castle secretly bringing out food for them, walder frey gave the men permission to start shooting as he only tried to kill robb and catelyn because they broke the deal they made, robb fell in love with another girl instead of his daughter

Guest was a wildling one thats good at archery, Guest was walking around the twins, stealing food from the freys as usual, she heard a commotion and ran towards the twins castle, she was greeted with a horrifying scene

Robb was already shot with arrows, laying on the ground, his mother was hiding under a table, his pregnant wife talisa stabbed to death laying on the floor, Guest reaches for her bow grabbing an arrow, Robb gets up and kneels over his pregnant wife's body, gently caressing talisas stomach as if trying to calm her down, somehow she was still alive, barely, the child in her was dead though

His mother ran out from under the table grabbing walder freys wife holding a knife to walder freys wifes throat telling them to let Robb go and then they could kill her

Guest sneaks into the building quietly slitting the throat of the men who shot at the, the bodies dont even let out a noise as she covered their mouth first, she lays them down gently before grabbing a bow and standing over to watch and wait
