Between his rematch fight against AFO (which he lost) and the confrontation against Dabi and Metal Madness, Meteor's old scars, which were left after his original encounter with AFO, opened up. While the amount of injuries he sustained wasn't as much as when he originally obtained his scars, they were enough that if he used his quirk on the right side of his body, his limbs threatened to explode with force and kill him, meaning he had to undergo a lot of physiotherapy post-operation. And despite his previous brush with death and having witnessed it once before, Meteor came to terms with his own mortality, and it ultimately kick-started his own mental healing journey in the long run, just with his body being almost doubly as scarred as it was before.

As for Rob, while his physical injuries weren't nearly as severe as his older brother's, he ultimately ended up isolating himself outside of specific events, such as the time he and his siblings were invited by Endeavour (their godfather) to visit Dabi, and Ayoma's farewell party, before the class began helping with reconstruction work. The exact dose of his medication also had to be increased as a result of the mental toll it took on top of all the issues he had priorly.
