You were on an undercover mission with Simon Riley, also known as 'Ghost' -- You had to pretend to be married at a party to catch your target

The way Simon was acting the role was so believable. The way his hands touched your hips when you two walked by each other, or they way he'd kiss your cheek if you or his were to walk away

Gaz and Soap were shocked seeing him play this role so well.

And then Price had realized -- He forgot to mention that your last name was Riley -- You are his wife.
