Lisa was always the one to remember anniversaries; three months since their first date, six since their first kiss, a year since their first date… she treated each milestone in their relationship as a celebration. Ianto had laughed the first time, until she’d told him that he made her so happy, she wanted to celebrate everything.
What Lisa wanted, Lisa got, because she made him feel that way too.
But Lisa’s gone, and now Ianto has to figure out the most important anniversary himself. Did she die a year ago at Canary Wharf, or seven months later at the Hub?
