Theo, perhaps sensing the impending physical explosion (or, knowing him, being aware enough to know of Draco's mental explosion), cut in quickly, clearly hoping to distract Draco from Blaise's admission. "She was injured, when they came to me. Physically and mentally. Very badly injured. We don't know how or why, but she's been unconscious since she came back. That's why we didn't tell you. We didn't know... don't know if she plans to stay. She can't... she's missing her core and things have been... hectic, to say the least. We didn't want to tell you until we knew more about what was going on and risk... anything. We didn't want to risk you. It was a mistake, we all know that. But we felt it necessary."
