Biography
Early life
Christina was born Cincinnati after her mother died giving birth to her. She was raised by her older half-sisters and father Joham along with her half-brother Blake who born the same day at the same time from a different mother. She has since then been on her own after reaching full maturity but has been close to Blake.
Full Of Surprises

Joham has been in contact with Blake and Christina telling them to keep an eye on his latest victim Tiffany Stewart who is pregnant with his child. The two of them try to find her at her apartment in Washington but she was not there. Blake and Christina were in the city of Forks when Blake detected vampires with special abilities around him. He and Christina came across the land where they found Tiffany, still pregnant, with the Cullens. Their arrival alerted Alice Cullen who saw them in her visions and the two took off in Christina’s mist before Edward Cullen and Lucas Stone could catch them. Blake and Christina returned to inform Joham of the situation. Joham has Blake changed Richard into a vampire to create an army of newborn vampires and have them distract some of the Cullens while Joham goes in and takes Tiffany's baby Lucina Stewart after hearing she is born. During that, Blake and Christina had some of the Cullens and the pack chase after them to lead them away from the Cullen house and both of them got away with Christina’s mist when Krystal Diamond nearly caught up to them. However, Joham failed to take Lucina because of Lucas and tries to come up with another way and Blake tells him that Lucina may possess a gift for a hybrid.

Christina escaping with her mist.
In March, Blake and Christina were ordered by Joham to try to capture Lucina again. The two of them did so along with another vampire and found Lucina by herself outside the Cullen house and captured her undetected by Christina's mist. As they were running however, Lucas and Krystal caught up to them due to Lucina's mental communication bypassing Christina's mist to Lucas. Lucas sends Krystal an aura sphere for her to throw it at the mist but before that, Blake got away while the accompanied vampire used is gift to transform into Blake to take his place. Christina and her partner were caught by the Cullens and after telling them that she honestly has no idea where Joham is, she was destroyed by the Cullens.

Christina's mist.
Christina has the gift to turn into white mist whenever she runs very fast. With it, she can avoid being detected by psychic gifts such as Edward's mind reading and Alice's visions and can also use her mist to the same effect on others. She uses this gift mostly to escape easily.
At first, Christina’s gift can only block out other vampire’s senses and also leaves behind a small trail of their scent but after awhile, Christina’s gift was developed to also block special abilities and leave no scent behind.

Christina is the daughter of Joham and the half-sister of Blake, Serena, Maysun, Nahuel, Jennifer, Jonathan and Lucina Stewart.
