Tony's POV:

Was I doing the right thing? I needed to tell her but then if I told her, she could get hurt. I had to tell her. She deserved to know considering I had been gone for 10 years! I missed her wedding. I mean, who misses their only daughters wedding because they were stuck in space? Only me apparently. And who misses their first grandchild's birth? Oh yeah. Me again. I had missed out on 10 years of y/n life and I don't intend to miss out on anymore.

I walked up to their door and knocked. I was worried. Would she believe me? Or more importantly, would she listen? Before I could think anymore, the door swung open. "Y/n, please. I will explain everything to you. Just please listen" I said before she could speak. She nodded letting me in. "Go through" y/n whispered while pointing to the living room. I entered and Peter was sat there rocking my granddaughter back and forth. "H...hi" I stuttered. "Mr Stark" Peter replied. "Please, call me Tony". "Um...Dad, what are you doing here?" Y/n asked me sitting down. "I'm here to tell you where I have been for the last 10 years" I responded. "Listen, you don't have to tell us if you don't want to". "Yes I do! I have missed so much in your life. I missed your wedding and I missed the birth of your first child! I owe you an explanation!" I blurted out. Once I said that I couldn't stop. Everything came spilling out.

"So...Thanos is still out there?" Y/n asked after I finished. I nodded and looked at the ground. Thanos kept me in space. He brought all of the Avengers there to bargain with us, but us being us never gave up. How we got back to Earth, I don't know. I'm still trying to work that one out myself. "I'm so sorry darling. I didn't want to tell you as I'm scared all of you will get hurt and after everything that he has done. But you deserved me to tell you that. But I promise, if he comes near any of you, he is dead. I promise to protect you all" I said. Suddenly y/n got up and flung her arms around me. "I'm sorry I pushed you away earlier. I love you loads" She cried into me. I hugged her tightly back. "It's okay. I understand. I love you loads too". She pulled away and walked over to Peter. "Bella, there is someone you haven't met yet" she cooed to my granddaughter as she brung her over. Y/n placed Bella into my arms. "Hello beautiful. I am your Grandad" I cooed while a tear ran down my cheek. I looked at Peter and y/n. "Thank you" I whispered. "Peter, thank you for looking after after my little girl for 10 years and thank you for marrying her. I always wished you would" I giggled at the end. We all laughed. "Your grandma would of loved you" I cooed while crying heavily now. "Wait. Would of?" Y/n stopped and questioned. I looked at her. "You don't know do you?" I said mortified. How could no one of told her? "Dad. What's going on?". She was worried now. "Happy told me he told you". I looked down at the ground. "We haven't seen Happy in years" Peter responded worriedly. I got up and put Bella in her Moses basket. I walked over to y/n and took her hands in mine. I was crying hysterically now. "Th...Thanos um... he killed your mother".
