Summary: Ianto hates lying to them, but he has very little choice. Ianto/Lisa. Pre Everything Changes.
He doesn't like lying to them, but Ianto knows that if they knew about Lisa they would kill her.
Lisa in their eyes is a threat and she is dangerous, but it's not her fault. She doesn't deserve to die because of something that isn't her fault; He holds onto the hope that one day he will find a way to reverse what happened to her because she wasn't fully converted that day.
No one knows the Hub better than Ianto it was easy to hide her away until the day some alien piece of technology gets brought in that can save her.
There are days when he's tempted to blurt out the truth and then it hits what they'll do to Lisa.
Jack would outright kill her, Suzie would do the same and pretend she was sorry about it, but Ianto would see in her eyes she wasn't. Owen would feel guilty about it, but ultimately in the end he would fire just as many bullets as Jack or Suzie.
Tosh, Ianto could convince her not to kill Lisa but her loyalty and gratitude to Jack would lead to her eventually spilling everything to him.
So he keeps Lisa has hidden away, he keeps his pain a secret. He wishes that had more faith in those he worked, but he has seen what they're cable off.
It doesn't matter with every day that passes his hope of helping Lisa is fading little by little or that some days his heart is filled with so much pain he could just curl up in a ball and start howling.
