Danny was young, sharp and there's no doubt that he was good at his job, but sometimes he was a little over anxious to prove it. He didn't fail to notice the glamour and excitement of being part of MI5, and sometimes it went to his head. However, no-one could touch him for surveillance skills.

After getting himself up to his eyeballs in debt, and committed to paying high rents for his luxury flat, Danny lost his flat-mate in a catastrophic operation. Luckily for Danny, Zoe agreed to move into the spare bedroom. Despite all their differences the two young Spooks made a good team, living together. It makes life a lot easier when you don't have to keep your profession a secret from your flat-mate.

Danny's confidence took a serious knock when colleague Tom was de-commissioned from the service and Zoe, whom he had deep feelings for, was forced into hiding with her boyfriend after an operation went wrong. Danny then met a sad and untimely death at the hands of a terrorist.
