Arabella, who saw everything, panicked. When Callis's body was thrown, her body turned stunned and she could feel goosebumps over her body as she could tell that there was the sound of a crunch of something breaking.
From how it sounded, it seems that Callis is someone close to Morpheus, and he had somehow tried to run away from Morpheus, which the latter didn't take it kindly. But she wasn't blind enough not to notice that this wasn't all that had happened.
The woman beside Morpheus, named Wanda, seemed to hate Callis, and that Callis hadn't tried to run away despite wanting to; instead, he was hurt by someone.
But Morpheus didn't seem to be in the state of wanting to hear an excuse, readily believing that Callis was going to run away from him.
