I really liked seeing Natalie handling an interrogation. We don't see her in the room very often, do we?
Not really, no. Her overall presence has been much more strongly felt in Series 3, though she still doesn't handle too many interrogations overall. (There is one more I can remember for sure where she dives in and really makes a hard play for information, leaving Matt to be the one to offer the witness a Kleenex. ;) I won't say any more though, so I don't spoil it.)
