No, he didn't attend Ianto's funeral. He'd attended enough funerals over the centuries to start feeling like a ghost, always the one left standing but never really included amongst the friends and family, standing at the edge of the crowd, grieving alone. After the whole thing with the 456, coming so soon after having lost Owen and Toshiko, he just couldn't do it again.

And, oh fuck, Ianto knows him so well. He grimaces a bit, and takes a while to meet Ianto's eyes. "I guess not. I kept myself busy, went off trying to find other people to help - other people to save." He gives Ianto a rather self-conscious look, because this is not how he's always tried to cope before.

"I figured it was better, at least, than trying to drown and fuck away my sorrows like I did after - you know. The last time."
