As with all Wolff members, Midnight has a second personality brought out with her silver eyes. When her eyes go silver, it can be noted that Midnight's personality changes. Midnight smiles all the time, but evilly. And when Silver- as Midnight calls her other personality- is happy, she often looks irritated or uninterested. When sad, Silver smiles happily, and when angry, Silver smiles evilly. On a rare occasion- Silver will actually smile, a genuine, soft smile.
     Silver has a habit of running a hand through her hair, caused by a few things. When stressed, both Midnight's personas usually mess around with their hair. Midnight plays with her hair a lot, but Silver will usually start messing with hers after physical contact, like hugging. She is known to put her hair up in ways she normally couldn't ever figure out, like a braid, when inspired by, watching, or had come into physical contact with a possible lover. (Gurl can't figure braids out to save my life tho. ;-; )

So yeh... I've had the whole silver eyes in the Wolff family for a while, but now it's implemented. :p
