Maybe, for 6a flashbacks, they can restrict them, as pointed out, to the new characters. One particular set of flashbacks from 2a (In the Name of the Brother) stands out as a good guideline. The story focused on Dr Frankenstein, without ANY interaction from the regular characters. it was simply Whale's story. and one of the better flashbacks of the series. Similar with Ruby's season 2 flashback in Child of the Moon. while Snow was involved, it was primarily focused on Ruby's story, not how she interacted with the other main characters in the past.
