(If the bandit closest to me was restrained, then yes). 

X'rax's firbolt goes whizzes past a bandit's head.

(You could get advantage if you went for the restrained one.)

(Then the restrained one was who I attacked) 

(I messed up.  I was directing that at X'rax, but he would have had advantage anyways from stealth.  I only asked Hansel for keeping track of who was damaged.)

(Also, X'rax would still have a turn.  That was his surprise round.)

X'rax

 Attack:  19

Melee Damage: 8 slashing or Ranged: 10 fire

X'rax and Hansel's combined attacks finish off the restrained bandit.  The only remaining one looks around nervously for an escape route.  Seeing nothing promising, he strikes back at X'rax (who could indeed get into melee range).

Attack: 21 Damage: 7

(X'rax is unconscious, right? Should I take my turn already? I kinda got lost on what the initiative was supposed to be...)

(Initiative is pretty flexible, due to the nature of PbP.  You go, then the bandits go.)

Nessie shouts, “Keep him alive!” And gets ready strike. 

Hansel is going to strike at the remaining bandit Attack: 5 Damage: 10

Falynn didn't need to hear Nessie's shout to run to help X'rax, touching his shoulder, and casting Cure Wounds 6

Nessie rushes the last bandit from behind after his attack on X’rax. She tries aim her strikes so that none of then will be lethal. 

Dagger attack7 Damage7

since X’rax is within 5ft Sneak Attack:6

Offhand dagger attack 12 damage:2

Nessie knocks the last bandit upside the head with her dagger hilts, dropping him.

"Maybe he can tell us more about the plague... or about other bandits..." she says to herself as she begins to tie him up.

She scans her companions and says out loud, "Now which one of you is scariest... he probably wont want to talk but I bet if we scare him a bit we could probably get something out of him."

As Nessie passes over Falynn while looking at the group, she shakes her head, indicating that she will not be a good option, and she responds when the Aarakocra stops speaking. "I think I might be too defensive for this. If you're not willing to do it, I'd place a bet on Hansel, he looks confident and tough, I know I was scared of him back at the tavern, until we started talking."

Already hoping her idea will be accepted, she casts Guidance on Hansel, to help in his interrogation.

(Forgot to mention, the Guidance Falynn used on Nessie was canceled the moment I chose to cast Entangle, which was just because of bad planning on my part.)

(totally forgot about guidance after i did well on my stealth lol.)

Nessie's feathers bunch at the mere slight suggestion that she would interrogate. Embarrassingly, she says, "Part of being an assassin is knowing your weaknesses. And you've seen me.. interact... I still have a lot to learn." she turns to Hansel, "Please?"

Edit: (is there is a tooltip for sneak attack? I was trying to figure out what term to put in but couldn't find the right one.)

(There is no tooltip for abilities of any kind, unfortunately.)

 "Do it Hansel," he whispers as he gently slaps the bandit awake. "Good say sunshine. My new friends and I were curious if you would know anything about the plague or if any of your companions are nearby. Now I'm not someone who would feast on a man's flesh, but I can't say the same of my friends. If you don't cooperate, I'll have to cut you up and feed you to them. "

 Intimidation with Guidance 17 3 (13)

Insight: 15

The bandit looks up nervously, and gulps.

”Er . . .well . . .my companions seem to all be dead.”

Another nervous gulp.

”I don’t know nothin’ about a plague, mister.  Please don’t kill me.  I was just tryin’ to survive.”

Hansel shrugs. "That sounds convincing. What do you know about Lance Rock?"
