Redfang thought about this and decided that if he bit Gleampaw and Pineleaf, no cat would know that he did it. He had plans to meet Ripplefur on the Streamclan border. 

When he got there, he said "okay, Ripplefur, in order for me to help you destroy Greypelt and his family, you have to help me."

"What do you need me to do?" asked Ripplefur.

"You need to help me kill Gleampaw and Pineleaf," answered Redfang. 

"Ok, so what do I need to do?" asked Ripplefur.

"You need to watch my back," answered Redfang.

"Ok. Let's go before it's too late. Med cats are early risers," said Ripplefur.

When they got there, they successfully snuck into the Medicine cat den and Redfang killed them both with swift bites to their necks. Then they snuck quietly away to wash themselves free of blood.
