Kafka "Project Bacon"'s Links
Kafka needs Escher around to feel safe. They trust them whole-heartedly, and when she's not stable enough to look out for himself, he'll always run to them. Being near them helps her ignore all the doubts and fears roiling deep down.
Escher would do just about anything to protect Kafka- including but not limited fighting, killing, or eating anything or anyone that threatens them. They escaped together and have remained largely inseparable, and she makes Escher feel safe and purposeful. Escher doesn't like the idea of being alone without him, and works hard to make sure that's never a possibility.
Toast is just as much family as Escher. Kafka has never once gone a day without feeling deep and terrible guilt for having to leave them behind. There was nothing she could do! He's so, so sorry! They don't know what else to do!
Bacon and Eggs left Toast all alone. All their shares of torture went to Toast in their absence. Toast hates them. Toast hates them. If Toast ever gets its hands on Bacon it will make him suffer and cry and kill them.
