It all happened when Remus asked Harry to be Tedddy’s Godfather. When Harry agreed, something in Remus changed. He didn’t knew what, maybe it was realising that Harry has become an adult way too soon, or how Harry agreed with such certainty to become his son’s Godfather, or how it was Lily’s eyes and Lily’s big heart who agreed and, James face who nodded while James voice said Yes. Harry who knew so litte about his parents and yet was so much like them. All of that suddenly hit Remus and he teared up. Without hesitation he hugged Harry. As he pushed himself away from him again, he mumbled: “I am so sorry Harry. I should have never left you alone.” Harry who tilted his head and answered with a look of confusion. “Harry, I want you to know that I tried to be in your life, I really tried, however i simply couldn’t get past your aunt. I even had a huge fight with Dumbledore about you, and why he doesn’t question Padfoot with the Truth Serum, but he just dismissed me.”
“Remus, I-“ But before he could answer Remus interrupted him. “NO please Harry. I… should have been there for you.” He grabbed the nearest chair, let himself fall on it, rest his elbows on his knees. “With Padfoot in prison and your parents dead, oh merlin Harry, your so much like your parents, it was my duty to be with you. I never ever had anticipated for you to know me as ‘Professor Lupin’, in another Life you would have had known me as ‘Uncle Moony’ and I.” He sighed, and started to softly cry. “I should have fought for that life more Harry.” Finally allowing himself to look at his nephews eyes, seeing that Harry also has watery eyes . “I owe your parents my life. James broke the law to be there for me, to see me happy. Lily was there for me in my darkest times, she knew things about me that no one else knew or knows. “ He stopped for a second, roughly wiped his with his fingers and took a deep breath. He didn’t even notice that he was shaking. “Harry I wan you to know, that I only became a Professor so I could at least be somewhat in your life. Knowing now what your aunt and uncle did to you, that was not nearly enough Harry and whatever they did, I know you don’t like to talk about it, its on me son. I could have prevented it, and I didn’t. I was so busy with my self pity, i abandoned you. I truly don’t understand how you still agree to be Teddy’s Godfather”. His last words were barely understandable as he was pushing them through his sobs. Harry grabbed another chair, dragged it close to Moony and took a seat. “I learned a lot from you, not only because you were my Professor but because you’ve become someone i look up to. And you definitely made up tor not being there when my parents died, cuz besides Hermione and Ron, no one was closer to me than you when Sirius died. For what its worth, I’ve seen you as Uncle Moony for a while now.” He rested his head on his Uncle’s shoulder. “How could I not become Teddy’s Godfather, I can’t wait to meet him”
