"You were there with her," Alana says. It seems to be what Abby has implied; she'd like to be sure of it. It's an important detail. Either way, though, it's easy to see how much this weighs on Abby. The years don't mean anything, they don't make it better. If anything, it seems like the passage of time might be making this harder on Abby. It sounds like her family and friends haven't been any help in that regard, and Alana knows how easy it is to bottle up feelings rather than admit to them and be told to keep quiet. The risk gets harder to take, and the pressure inside gets too high; it always blows up sooner or later. It's a bomb that needs defusing.
