I don’t even think it’s really Drarry. I think it’s more that Harry cares a lot about everyone… including his enemies. He never even used the killing curse on Voldemort remember?
You’ve got your mother’s eyes were the last words Snape said, then he died. you’ve been there all along to help Harry, more loyal than anyone, loving Lily, her son too. He might be strict, but behind those eyes is a wonderful loyal person willing to sacrifice himself for a friend, while Dumbledore was using Harry as bait, and asking things for return from a friend who had feelings too. Dumbledore seems nice, but sometimes, he is just not a true true friend to you. Snape was his spy, could’ve died doing that just to protect the woman he loved. Snape is one of my favorite characters, because he is loyal, sweet, strict too, but a mask to hide away all the loyal traits about him, his actual, true face of personality revealed at the end. So, saying, “I didn’t want to kill him. I had too though. I miss Albus too. I… I couldn’t disobey though. “hid away in teary eyes, he was actually a great person. I miss him along with sirius, Dobby and Dumbledore. Rip Snape.
