The temperature seemed to drop several degrees in the icy cave, which had already been freezing.  All the dragon's jaws dropped down and Island looked at Snowskull in disbelief.  "I-i don't have a brother." She said, her smile fading, she was taken back by the sudden tense feelings in the cave.
"Snowskull can I talk to you for a minute?" Searing asked quietly. "Ok..." Snowskull said and followed  Searing to the corner of the cave. Sharp stalagmites and stalactites were poking out at them as if in an icey prison. "What do you think you're doing?! Stop saying nonsense!" Searing whispered to Snowskull.
"Island has enough going on, don't be putting fake things in her brain. Who really is this dragon?" He demanded, looking his snout down at Snowskull.
"He is her brother, I promise you."
"Where's your proof?"
Snowskull turned away from Searing and faced the other dragonets. "I don't care! How could you never tell me!" Island was shouting in Bermuda's face. "I can't speak to you when you were an egg, Island!" He replied harshly. I
Island looked like she was about to burst in tears. "I don't know who you are and what you want, but you are definitely not my brother and I can't believe you would think I was that stupid to believe it."
Searing glanced at Snowskull and she caught his glare. "Island, listen, he has something to tell you." Snowskull said looking at Bermuda.
"Ok, Island, look." Bermuda said. "Beluga took you when you were an egg. There was a war dragons were dying, and mom wanted to keep you safe. She gave you to Beluga and Beluga brought you here, as you were part of the prophecy. Before any of you ask, I know this is the right dragon. She is the only dragon named Island and Beluga said he wouldn't change it. So, I'm your brother."
Island stared at Bermuda and Snowskull was struck with an idea. "I know where I can get proof." She said abruptly. "We need to get Beluga down here."

                                      ...

Beluga came down and he stared at all the dragonets and Searing. "What is going on? Who is that?" He asked, pointing at Bermuda.
Bermuda trotted over to Beluga and stared him in the face. Beluga gasped and everyone whipped their heads towards him. "Bermuda?" He whispered. "Yes." He answered.
"It's you! It's really you?"
"Yes, Island's brother."
"Oh my- I never thought I'd see you again."
"Me either." He put on a crooked smile and tilted his head at all the dragonets.
Island slowly walked over to Beluga then she stretched to her full height and punched him. "Ow." He yelped. "What was that?" Bermuda asked her. Island directed herself to Bermuda and punched him too.
"So he's really my brother and you never told me I had one?" Island asked Beluga sadly.
"Listen, I never told you because I didn't know if he would ever return or if he was even alive. I couldn't bring it up. Your family means so much to me and if I lost someone else and told you he was alive and he wasn't, thankfully he is,  it would've been heartbreaking."
Island looked up. "Wait, lose someone else...? What do you mean?"
"Island, your mother is dead."
