The young intelligence analyst will leave Eric (Barrett Foa) alone in Ops once more as she pairs with Granger (Miguel Ferrer) outside the office.

However, it also sounds as if at least one half of Nanger may find themselves in a bit of a jam.

"Just saw my driving stunt double. Don't know why I need one. I've crashed plenty of cars," Ferrer joked on Twitter.
