In the Shrieking Shack things unfold unexpectedly : Ron sits on a dusty, ragged couch clutching his hands together, where before he held his pet rat, while Hermione and Harry stand defensively in front of him. Professor Lupin enters the room suddenly and simply stares at the gaunt figure that is escaped prisoner Sirius Orion Black. He stares for a full two minutes before a large grin breaks out across his face and he rushes forward and the two thin men embrace tightly. After a few moments Lupin pulls back enough that he is able to kiss Black passionately.
The Trio stare at the two men shocked and can only watch as the couple kiss; only breaking apart to breathe. Ron and Hermione are upset at the supposed betrayal of their professor, but Harry is angry at this final breach of his trust by one of the only adults he thought he could trust. Exhausted from the magical glamours he has in place to hide his battered and malnourished form, and emotionally drained from the night's events, Harry forgets to hide his greatest secret: his abuse.
"What the hell was that ?"demands Harry "I was finally going to tell. You convinced me that I could finally tell you and Snape the truth. But of course I was wrong to trust another adult. Snape has been the only adult that has been truthful with me. Why does it always have to hurt so much to be let down time and time again." Harry murmurs that last part seemingly to himself.
Sirius and Remus, who had jumped apart at the loud and harsh voice of their godson's demand, look at each other in confusion and concern. They look back to Harry, who seems near tears, and can see the vast amount of pain in his eyes, and realize that they need to explain before Harry is hurt anymore. They file what Harry said, about telling Remus and Severus something, away for later questioning.
"Please Harry, before you judge us too harshly, will you please let us explain what really happened ?" begs Remus.
"... I'm listening" replies Harry after a pause and several minutes of silence.
