18:48 - 19:55 Goku seems done-for until Krillin gives a minute-long speech that's cut from this video. He eventually, with some difficulty, gets back up for the sake of his friends. Jiren is shocked and says Goku shouldn't even be able to move at this point. He asks how many times Goku has to be beaten before he stays down, Goku responds he can't fail when his friends are depending on him. Jiren says friendship is meaningless.
19:56 - 20:22 they reengage. More ATATATA with neither landing a solid blow, bar one punch from Goku. This exchange breaks off when Jiren lands a kick that sends Goku flying.
20:23 - 20:37 Goku recovers from the kick in time to dodge Jiren's second. He lands some punches to Jiren's gut, which sends him flying in turn.
20:38 - 20:50 Jiren recovers and throws a bunch of ki blasts, which Goku dodges, before delivering a powerful blow to Jiren's chest.
20:51 - 22:12 pause, "FRIENDSHIP IS MEANINGLESS!", Jiren tries to kill Goku's friends.
22:13-22:19 Goku gets a Nakama power-up and punches Jiren in the face.
22:20 - 22:57 ATATATATA with neither landing a blow.
22:58 - 22:33 Goku dodges one of Jiren's haymakers and uppercuts him. He follows up with a Kamehameha, which Jiren screams in pain struggling against until he's overwhelmed. FINALLY, for the first time in the entire fight, Goku has a decisive advantage. Jiren has been knocked down.
22:34 - 24:49 They exchange some dialogue and Goku, now on the winning end of one of these exchanges, prepares to knock Jiren off. However, when he tries to take another action in MUI, the strain is too much for his body and he promptly collapses in agony, now in base. Whis explains that Ultra Instinct's power was too much for Goku's body to handle (not in this video).
24:50 - 25:37 Jiren, who unlike Goku can still stand and fight at god-level, gets up and apologizes to Goku for his inevitable erasure. He pulses the ground near Goku to send him flying out of bounds without killing him.
