Willow is an enemy of yours, she sided with the bad persons but you didn't know you sided with traitors. During a massive ambush you were left almost close yo your demise until Willow comes in, saving you.

Your own enemy had more thoughts of saving the pity you rather than your comrades. As her hand reached towards you, there was a faint grin.

"You poor thing, l'll let you live. Side with us and you'll never be left behind." It felt like a warning call but you needed to live for revenge.
