At this point in the story while Guts' core companions are all aware of Guts' current objective and the basic nature of his and Casca's brands, most of them are still unaware of Guts' (and by extension Casca's) past during the Golden Age arc. IIRC the only member of the current party who could be considered as fully in the know of Guts' past is Puck (who learned about Guts' past with the Band of the Falcon from his couple of visits with Rickert and learned about the specific details of The Eclipse with Rickert when Guts told them off panel during episode 181) and then Schierke seems to have some partial/vague awareness of Guts' past due to her knowledge of Griffith's true nature and Flora informing her that Griffith was one who branded Guts (and Casca) in volume 24 and then later was exposed to fragments of memories of Guts' past with the Band of the Falcon and The Eclipse when she dove into his ego during volume 27. Everyone else I believe is currently basically unaware of Guts' (and Casca's) past.
However, due to narrative convention, it seems probable that Guts current party will eventually become informed of his and Casca's past eventually. However, since Guts still isn't the type to open up about his past (even when his companions were unknowingly discussing his history with the Band of the Falcon during Episode 244) it still seems up in the air exactly when or even who, will end up spilling the beans to the current party about Guts and Casca's past. Will it be when they reach Elfhelm? Before or after when Casca is (presumably) cured? Or even after that? Will Guts not be the one to volunteer the information? Could it be done second-handedly through Puck? Or maybe a cured Casca will be the one to tell their history?
Does anyone else have their own thoughts and/or ideas on this topic?
