I think a bunch of them are from various flash backs in the various Fate adaptations- but there was also a short series paterned off of the help screen. In Fate Stay Night Taiga and Illya host the help screen after bad ends with Illya being Taiga's first student, I can't remember what it was called but there is a short series where a younger taiga works with Illya's mom to do the same thing, Where they act as therapists for the various people who died in Fate Zero. Of course the evil in the grail slowly reveals its influence and the whole thing ends with Taiga being sent to leave and wake up and then she remembers she passed out after either choking or eating something expired while camping. While wondering about the weird dream she finds a old worn down version of the sign the help room had and takes home with her.
