Spinel gave Aquamarine's words some serious thought.  [i]Did[/i] she trust her?  About as much as she had ever trusted anyone, which admittedly wasn't saying much.  What [i]had[/i] caused her weapon to materialize?  She thought as hard as she could back to the first moments of her existence.  She remembered how comfortable, how natural sitting there in absolute silence with nobody else around felt.  She couldn't imagine feeling more at home, but that wasn't what brought out her weapon.  She thought about the spiders, about her new companions being attacked while she hid.  What went through her head at the exact moment she drew her weapon?  [i]I can't just let them die.[/i]  

Spinel understood the gravity of the situation.  She was aware that she had no idea what she was doing, but she was confident that, out of anyone there, she was the most capable of forgetting herself.  In some situations that might be useless or worse, but it was what the situation called for now, because it would make it easy for her to let Aquamarine take control and do her job.  Spinel knew what to do.  She couldn't just let them die.  She gave Aquamarine her hand.
