Fridge / Gabriel Knight

• Fridge Brilliance: Novelisations of the first two games were released, but never the third. In-universe, Gabriel writes two Blake Backlash novels based on the cases he encounters in Sins of the Fathers and The Beast Within, but it's implied that between his depression over Grace leaving him and his full-on breakdown as of Temptation that he never got around to writing a novel based on his experiences in Blood of the Sacred, Blood of the Damned. Hence no novelisation of that game, perhaps?
• Fridge Horror: In GK 2, Leber tells Gabriel an account of a runaway teenage girl who was seen going into the forest before being taken by a large black wolf. Considering the girl's reported beauty and the killer's identity with the forest very close to a certain hunting lodge, it's entirely possible the victim did not enter the forest randomly but was instead seduced into a meeting and betrayed with a horrific revelation.
