Action
Jack doesn't come along until later in the day, because Ianto was all about heading off to the cemetery to handle it this morning and, even if he's not sure if he should be worried about this new closeness between Spike and Ianto, he's sure it means Ianto's much better equipped to handle Spike than he is.
So it's not until evening that Jack wanders over to the cemetery to see if Spike's still there and, if so, if he's drunk himself unconscious yet.
