A.) Jasper and Rosalie are the only ones who look like they could possibly be related by blood.
B.) If Alice & Jasper and Rosalie & Emmett are going to date, then Rosalie & Emmett can't have the same last names, same with Alice & Jasper... otherwise, to the public, they'd be dating their sybling.
So no, they're not related in any way. It mentions that Rosalie was the only daughter of her parents - and her and Jasper lived in totally different times.
Jasper's real last name was Whitlock... not Hale...
Hope I could help!
Edward is not with anyone in the family so he could have the last name of cullen. Alice is with Jasper and if they both had the same last name that would be weird so he and Rosalie (who is with Emmett cullen) have the same last name.
Logical reasoning, but nothing says that someone can't elect to keep their own last name, yes? At one stage, Edward posed as Esme's younger brother, so it isn't a necessity that he take the name of Cullen.
It's true that if they had the same last name it would be weird but they're all 'adopted' anyway, and they have the same 'mother' and 'father' so it's not that less weird, really.
In any case, Rosalie doesnt want to completely forget her human life since we know about her nostalgia with being human and wanting a normal life. Her last name is a reminder of her past. Jasper and Rosalie are not related as humans though.
Rosalie wanted to keep her last name in remembrance so her last name is not Cullen. Rosalie and Jasper are twins to any non-vampire, but they're actually not related (Jasper was created and born a long time before Rosalie was). Jasper took the last name of Hale to give their family more credibility. Their story changes over time.
Well Rosalie wanted to keep her name so the Cullens let her keep it and Jasper kept Hale as well since they were like siblings but they could also give the family more credibility. Also Alice and Jasper are a couple as well as Emmett and Rosalie. They can't have the same last names if they are dating because then they would be siblings and that would be weird.
Jasper and Rosalie have the same last name because humans think they are twins and so they go with what the humans think so people won't get suspicious.
Jasper's real last name was/is Whitlock, but he took Rosalie's instead.
No they are not related in any way except that they are in the cullen family. Rosalie wanted to keep her last name yes but it goes deeper than that. Carlisle and Esme are married so they can have the same last name. Edward is not with anyone in the family so he could have the last name of cullen. Alice is with Jasper and if they both had the same last name that would be weird so he and Rosalie (who is with Emmett cullen) have the same last name.
wow your stupid.
