Oh, this was fabulous, you’ve done a wonderful job building the creepy atmosphere! I love how it’s a bit spooky from the start, how Sirius’ dreams and his thoughts and feelings about the situation in the wizarding world back each other up, in a way, and draws me as a reader into Sirius’ mindset.
I love the interactions between Sirius and Remus as well, and the ending was clever, as well as sweet in a way the two of them definitely deserved after this ordeal. Great job! <3
