Nothing Changes

When the crying stopped and all that was left was the quietness and time to think, Gwen tried to remember her friends at their best, like people say you should do. As her mind wandered, Gwen caught the memory of Toshiko with Tommy, and smiled at how in love that girl looked. But the smile was soon gone when another memory from that day came forth, or more precisely, a phrase.

Jack never stops saying that this is when everything changes, but what she joked about that day, which of course Ianto turned serious and solemn, was the truth:

Nothing changes, or at least, not when you work for Torchwood.
