Since Katherine woke up over an hour ago, she held herself well despite being reminded of Chris's death. She didn't want to dwell on the fact that Chris died four days ago while saving her. It wasn't because she disregarded what happened, but the thought of it was just too painful—she didn't think she deserved to mourn.
It was like having a crack in a dam within her. A crack that she tried to ignore even though the water was already spraying out of it.
However, hearing Damien's news regarding Gus just made that crack grow bigger. Until she could no longer hold it in. How did this keep happening to her? People always died trying to save her. She was then reminded of the time when Parker tortured her, and he let her listen to a recording that happened during the night when their house was invaded, and her parents were killed.
The sheer memory of that painful night caused an old scar in her heart to bleed once more.
