RGBY don't know that Chosen has been renamed/had his powers stripped.
And RGBY don't know that Victim attacked Alan, and potentially bricked his computer.
Both of the strongest allies they could potentially try to call upon have been severely kneecapped, and they don't know that yet. They don't know neither of the two can help them with the Dark Lord again.
They're clueless that there's literally no one to call for help like they've done before.
Alan in particular, if he manages to get his computer back up and running, would probably be VERY HESITANT to answer any pleas for help from Yellow after Victim's trick.
They don't know it's just them and the Mercs and Mitsi this time.
And that's prolly really scary, considering they've already lost and died to TDL before, and the only other powerful foe they've faced before this was someone they also never actually won the fight against; they only 'beat' King because King gave up.
TDL is not gonna do that. He's either gonna go down fighting to the very end, or they'll need to figure out another way to force him into submission. By themselves.
Where one wrong mistake can get any of them turned into an enemy.
God, their situation is so bleak.
I know they're gonna win and be fine bc AvM Season 4 starts like, literally a month after AvA Season 3 ends, which is honestly super funny in hind sight, but GOD, the stakes have never been higher.
