[ Luckily there isn't much research for Ianto to do. If anything Spike wants this discussion to be had, to get it out in the open rather than tip-toe around it. He can keep his personal relationship with Tyki out of the way, but he can't ignore that they have a bond because that bond is exactly what could make or break this thing. ]
