It doesn't have to be all filler... and so long as they don't perpetrate the ultimate filler Sins(no time for it to happen in canon where it should happen, OoC interactions, in other words, it cannot be canon because it contradicts existing canon), filler isn't that bad... and as we have like half a semester unaccounted for there was plenty of time for it to happen already if they cannot do that further in the timeline.
