sienna suarez was considered to be a mistake, as told by her grandmother multiple times. ever since she was could understand english or spanish, she can't really remember. charlie and sienna's mother sarah met when sarah was going through a breakup with her boyfriend of 6 years and xharlie comforted her, in another way than normal. that night sarah had went back to her hometown across the road of texas while charlie stayed in forks. that was until sarah found out she was pregnant, she kept it as a secret from charlie for 8 years before her father begged her to tell the man about his daughter. sarah drove to forks when sienna was 8 and told charlie everything, charlie was angry as he should have been in his other daughter life. sarah apologized saying that she was scared that he would tell her to get rid of their child. sienna and charlie got along well, better than sarah's husband jeff. sienna didn't have a particular feeling about bella, she knew they were sisters...well half sisters but she didn't like or dislike her. bella didn't believe that her dad would be so careless like this, she didn't believe that sienna was her half sister. and she thought this for years.
