From TvLine:

NCIS | Traditionally, NCIS starts up production in early July, so one would hope that word will break soon about Pauley Perrette, Michael Weatherly and Sean Murray signing on for Season 10. But when we saw Perrette on Tuesday night at the Thirst Gala, she was (charmingly) coy. Asked where things stand with her negotiations, all she would say is: “I love my job!” And as for what the premiere might look like, given that most every character had been left in jeopardy, there was little to dish. “We’ve seen no scripts — the cast has seen nothing – so we have no idea what’s going on,” she shared. “We’ll see.” On Perrette’s wish list if she does re-sign is further exploration of Abby’s relationship with her brother, which was touched on last fall. “The fans want that too,” she said, “so I think that will happen.”

From EW.com:

PLEASE tell me there’s something in store for Abby this season on NCIS. There wasn’t nearly enough of her last season. — Lorie
If that’s how you feel, good news! According to Pauley Perrette, who we caught up with at this week’s Thirst Project gala, this season will not only see returns from Abby’s brother and bestie (played by Meredith Eaton), but it will also take us deeper into her life beyond NCIS. “The only thing I do know in general [about the season] is we’re going to go a little bit more into Abby’s life more. People have been asking for it for a long time,” she says.
