"Oh Sirius." To be accused of something terrible as that must be awful. She can't imagine what it must be like to be framed for the death of someone she held dear to her heart. Let alone for such a long time. That's exactly what Sirius went through though and it makes her heart ache for him. "I'm so sorry."

She reaches out to rest her hand on his shoulder, hoping the chill of her touch won't be a deterrent for him. Due to not having her gloves on she needs to put more effort in her action and she does. She really does for him.
