Obviously that would be by mixing it with the other storylines... the entirety of RNJR should feel some guilt/responsibility for Pyrrha, as well as general loss.

There will probably be at least an episode on the way to Mistral where they all face the loss/guilt, possibly including the village NR want to go to, I expect Pyrrha's parents will come in on either a continuation or counter point of that kind of episode later on.

For skill/leadership I believe again Jaune should be going on this journey along with Ruby, who is no doubt somewhat reticent leading after her team was dissolved. I expect season 4 to focus on this and go from R&J doubting themselves and their leadership to Jaune stepping up with the support of Ruby to lead his team and finding the courage to call Ruby out and bring her to setting out to reassemble RWBY either in the season or at the end.

For Jaune's Arkos arc I believe he should at some point break down and hopefully confide in Nora, allowing Renora to simultaneously get pushed forward while Nora confirms to Jaune that Pyrrha did love him(providing Jaune closure) while realizing she cannot live with chancing the same doubt be felt by Ren.
