1st round: monster goes on 15, fighter on 10, you go on 7. Monsters acts, fighter acts, you use surge on you and do your other actions.
2nd round: you act at 27, thus gaining a turn on the monster.
Case 2: You go on 20, monster at 18, fighter is surprised. You cast surge on the fighter, that will go first in the following round.
Great analysis KA, I second everything you said here.
I am credible! Proof below!
