(He isn't, that's just the way his biology is. They're in the hospital about to go visit Nightshade, Ridley's character, who was severely injured and is in a medically-induced coma.)
"oh yes, I had better tone down my appearence" *neoshadows wings retreat into himself, the bands and smoke receding into his body*
*"No Raven, I won't hurt him, just remove him from your presence and place wards against him to prevent him from bothering you"*
"We'll just have to see if you have to," said Raven. "Neo, can you be good and wait outside the room?"
"That would be wise," Silver said as the elevator door opened. "My daughter's injuries are not your idle amusement." A entire week without sleep was taking its toll on the old Bat. His ears drooped, his mane and tail were unkempt, and dark circles had formed under his eyes. "Why are you all here?"
*"Silver, are you ok? if you want I could procure a berry that'll help you? I don't know if it it will work for Nightshade though? "*
"I just wanna see her," Raven said simply. "Saber's here 'cause she drove me, and Tentacles is here... for some reason."
"I am fine," he answered. "I am... tired." He nodded to Raven, ignoring the others. "Very well. If you wish to see her, you may." He turned and walked back into Nightshade's room, where she lay unconscious and wrapped from head to tail in gauze.
Asmo decided to wait outside the door. "Sweet Luna..." Raven's ears flopped down as she walked in and looked down at Nightshade. "Is... do we know if she'll pull through?"
Silver pulled a small hypodermic syringe from his bag and jammed it into his neck. "Thank you, Arch, but I have my own... grrrrAAAHHHH!!! ...solutions." He pulled out the empty syringe and tossed it into the trash, then turned back to Raven. "Her injuries were severe... lethal, for a normal pony... but her body will heal with time. It is her mind that I worry about. The brain damage was extensive."
"Oh, no..." Raven sighed. "Take her back to the bar to see Dusty when she's up. If anypony can help that, it's him. Part of me wonders if you should've left her with Az."
