Anti-Hero: She's a bit cold emotionally and has a definite mean streak, but there's no question she's one of the good guys.
Badass Longcoat: Arguably subverted; despite her competence at her job, she's nowhere near as badass as she presents herself, a fact that becomes apparent after leaving Romdeau. This is bitterly lampshaded by Iggy after he contracts the Cogito virus, when he calls her out on acting like a badass government agent when she's really kind of a spoiled brat. Just how accurate this is is ambiguous, however; it could just be the rantings of a wounded friend taken for granted for too long. And despite all that, she still remains tough as nails throughout ensuing events.
Super OCD: It's been speculated that Re-l might have OCD, judging from the way she conducted an earlier investigation of Vincent's room (she lined up a cup on a stand in the mirror image of another) and the way that she behaved in episode 16. However, the former case could be the result of years of strict government training and the latter a result of Cabin Fever.
When She Smiles: At the end of episode 16, upon seeing Re-l give a true smile, Vincent is seen blushing.

Become A Real Girl: See Meaningful Name. It's kind of implied that this does happen in a literal sense, and it's necessary for the series to have a happy ending of any kind as otherwise, she'd be killed by ultraviolet light like all autoreives.
