I might have some explanation for some of the issue with the latest chapters, but they might not be the best
1.Kassandra plan
I'll admit I said that I did think that it was dumb, since it probably would've been easier if they just let Sera freeze time or if John copied a teleport ability and teleported behind Orin
But looking back I think I know why they didn't have Sera or John Grab Orin, because for all she knew they could've just grabbed Orin and then ditch them,
She even says in one of the previous chapters "who gets to keep him" also theres that chance that one wrong move and they would've been under Orin's control
2.Sera not using Time freeze to get to Orin and John not teleporting behind him
I understood why John couldn't teleport since some sheild and barrier like abilites appear to block out teleporting
I was confused on why Sera didn't freeze time, but I think there might be some explanations, sheild and barriers abilities might be able to block out time freeze, and even if they can't block out time freeze it appears that if Sera hits something hard enough it might force her out of time freeze
also it might not be possible for Sera to use or stay in her time freeze mid air, but then that leads to the question of why attack from above in the first place
3.why didn't the attacks of 3 God tiers break through Orrin defenses,
I didn't have a problem with this since I think depending on their levels it might be believable that Orins defenses are strong enough to defend against them,
Elite level defense seemed to be effective in groups caused either A the opponent would be forced to spread out their attacks or B they can band together to increase their overall defense,
Then we have the Bubble sheild(s), which is most likely a high tier level abilite(s)
And then we have Orrin himself who's mental ability appeared to be affecting Arlo through his barrier, and so it might be affecting some of the other characters as well making their attacks weaker
now this mainly depends on the levels of the defenses because if it turns out all of the sheilds Surrounding Orrin we're just elite level, then I can't really defend this since the combined attack of John, Sera, and Kass, even if Orin was weakening them, should've been enough to obliterate the sheilds/barrier(s) around Orin
