So obviously that gorgeous lady up there is Dianna Agron, but that face claim is by no means set in stone. If you want to use another, equally gorgeous, lady, as long as she's blonde and you run it by me first, we're golden!
Now, we did have someone playing the fourth Watkins sibling, whose account is here should you wish to have a gander.
Basically, the only things that are set in stone about this character are things that were previously set in stone, so no need to worry about her having been previously played!
So what is set in stone? Well, not a lot, really. The traits listed above, definitely. She's the youngest of the Watkins siblings, all of whom have been adopted. Jason is the oldest, although he was adopted last, which is ironic since [Dianna] is the youngest, but was adopted first. Of the kids, she's the most like Zack (account here for you to check out). While she and him are both quite sensible, Cameron (account here) and Jason are not. Cam lives with Jay, and they're pretty tight. He looks after her and all that shizz. More recently, it turns out that they actually have the same birth mother. Gasp! So anyway, I don't know how [Dianna] feels about their relationship, but things with Zack tend to be a bit terse. Jay is a douche a lot of the time, and Cam just doesn't think. So yeah.
All that said, she knows she's loved, definitely. All three of her siblings would go out of their way to do anything for her, and their dads (plural, gay) are exactly the same. Jay probably sends her things randomly out of guilt, and he'd also send her money if she ever needed it. I don't think they exactly see eye to eye on things, and I think it'd kind of be amusing if she acted more like his mother than his sister? More a motherly/mother hen type role than an actual ~she raised him thing haha.
Sooo uh. Yeah. That wasn't concise and it's all a little complicated, but we would all LOVE to have the final sibling!!! Really. Anything that I haven't specified here is more or less up to you, within reason. Obviously feel free to hollar at me if you have questions. And yeah, that's it really.
Pretty please take her? <3
