The consensus reached (re)affirms the following rule as formulated by CzechOut: all sources with multiple endings, or indeed mushy middles, are invalid.

This directly follows from Rule 1 of T:VS: "Only stories count". If there are different endings (or different middles, or different beginnings), it is not a story, it is not a narrative. Thus, it cannot be used as a valid source.

The consensus opinion explicitly names Attack of the Graske as invalid.
