An illogical interrupt would be like Evvie seeing someone aim a gun to shoot her so she shoots fire that hits him before he can fire his gun, and there's no indication that she's that much faster than him. Most illogical interrupts have to do if the character does not have the reaction speed or time to carry it out. The only other illogical examples I could see is if they do something they couldn't anyways even with the required time, but that's just a straight out illogical attack.
