Started to rewatch the series from the beginning with my family. Noticed that some of the episodes are very "filler" and with worse animation (like s1 13 or s2 2). Can somebody please give me a list of similar episodes that you can skip? Asking because there is time to watch only one per evening, so I would like not to waste time. Thank you in advance for understanding.

I had a dics of the complete series but for some reason I had 2 season 5 and no season 2 so I’ve been wanting to watch it

During the last battle, when Jack realizes Ashi has the same powers of Aku, Aku counters that if he goes back, he won't just kill Aku in the future but completely erase Ashi as well. Possibly all of his comrades as well via butterfly effect. Jack freezes in horror from this revelation until Ashi fiercely kisses him, asks him to never forget her before opening a time portal as the Scotsman's ghost grabs Jack and hurls him through it, enraging aku into violently assaulting his daughter.

Back in the past, realizing the sacrifice his friends made, Jack swallows his sorrow and finally defeats Aku. In the future, Aku's defeat in the past causes his body to be consumed in a blinding light that spreads over the entire world:

Scotsman: 'E did it!!

Ashi: Jack...thank you.

Upon returning victorious to his homeland, Jack's victory is a heavy one as it required the possible destruction of not only all of the friends he made but also the woman he had fallen in love with, until his father the Emperor reminds him of the nature of rebirth and how his memory still tethers his soul to theirs. As they go off to meet the envoys from other lands, Jack encounters strangely familiar individuals (the preincarnations of his friends from the future) including the daughter of one of his fathers subordinate daimyo, who bears a striking resemblance to Ashi.
