Something warm flared in Ianto's stomach at the sound of Akihiko's voice. He was glad that he had a partner in looking out for Jack, because god knew that Jack was never going to start looking out for himself--there was always someone higher on his list of priorities when it really mattered.

"He is a stalker," Ianto confirmed. "He tracked Jack through time and space just to get together. And he's still hanging around even now, like he's hoping that Jack will come to his senses and realize all the good times they had and come back to him." Ianto fought very hard to keep the aggressive and slightly jealous tone out of his voice, and it almost worked. He knew better than to be jealous of past lovers of Jack's, but there was something about Hart that made his hackles rise.

"The point I'm making is that Jack's been on this disappearing act since Hart showed up, but he hasn't said a word about it to me. And he isn't in his usual hiding places--I've checked all of those." Ianto frowned. "John would boast about it if he'd for some reason gone to him, he's not exactly the subtle type, so..." Ianto glanced up at Akihiko. "So, I'm worried, and it's as stupid and simple as that."
