The wolves in forks are not werewolves but shapeshifters.
In the woods near quileute tribe Billy was sitting in a wheelchair and behind him were were the wolf pack gathered ready to protect him anytime.
Billy looked at Carlisle and Esme infront and asked "what is it that requires you to come here late at night Carlisle?".
"A friend came to stay in town."Carlisle said to Billy.
Billy frowned and asked"friend?".
"Yes, old one"Carlisle said to Billy who was still frowning and said"don't worry, he isn't a cold one."
Billy looked relaxed when he said he wasn't a vampire and asked"Then why are you here?".
Carlisle looked at Billy and the wolves behind him and said"But he is more dangerous than a vampire."
Billed looked confused and concerned and the pack behind him aslo seemed to feel it so they bared their teeth "Who is it?".
Carlisle looked at Billy seriously and said "His name is Leo and you should have heard of him."
Billy looked shocked and tried to stand but fell down due his broken legs.
Jacob who just came here looked at Billy falling on ground and ran to support him while shouting"what happened?".
But Billy looked at sam who turned into his human form and asked him to take Jacob away.
Sam dragged Jacob who was still angry to the house while the rest of the pack stayed.
Billy looked at Carlisle and said "You mean Leo, the immortal human."
"Yes its him" Carlisle replied calmly.
Billy looked at calm Carlisle and questioned "why did he come here?"
Carlisle looked at Billy with worried look and said with a smile "i don't know why he came but i can guarantee he didn't came here for trouble".
Billy looked still concerned and asked "where is he now and how long will he be here?."
"He will be staying with us and he doesn't have any plans to leave for now" Replied Carlisle.
"I came here to inform you because I don't want lose my neighbours for provoking him without knowing him".
"And I hope you will inform everyone in your tribe to not to anger him" Said Carlisle looking at the wolves and left.
Billy looked at leaving figures of Carlisle and Esme and said to people behind him who transformed into human to push him into main hall and gather everyone for a meeting.
Carlisle and Esme were running at vamp speed back home when they encountered Edward and the group who came out to hunt so they followed them to hunt.
While the cullens were hunting and Billy was informing everyone in pack about Leo and to be cautious to not provoke him.
