It's pretty shocking to see Ianto take care of the aliens so quickly and effectively. I can see why Andy is so surprised at seeing this side of Ianto. He's not usually like this but it's a nice change. Andy still has a lot to learn when working for Torchwood. I think he's the perfect new addition to the team.
Author's Response: Ianto may appear mild-mannered but he can be kickass when it's called for. He'll teach Andy what he needs to know, and Andy will be an excellent field agent once he's done. Thank you!
