Deshi shouts, "There is no need for bloodshed! Master Hippo- kindly release the captain and we can all sit down and engage in a reasoned disc-"

Penny turns, “Yes, but let us release him in the car behind us, not this one!”

Deshi thinks for a moment. "Yes, that would be wise." He calls over to Penny as the guard continues to stab Roland. "Deshi just feels terrible about all of this. Do you think he would sheath his weapon and let us pass if we explained that we simply intend to disembark?"

The raven perched atop Deshi's staff craws a bit and nods its head at the reasonableness of the tortle's suggestion.

Here’s the scene. Giant hippo man eating an officer, while another stabs at him, people screaming and fleeing while Ormond wades against them, giant turtle waxing philosophical as an island of calm in the aisle, and Penny standing in a seat, watching it all. “I do think we might be past the discussion stage, friend turtle! But they might see the wisdom of your words after some time cooling down. In the aft cars!”

Ormond is impressed with how quickly everyone talks. Seeing the unfolding situation, he just yells out, "Subdue them!" As he wades through the crowd closing in on the fight, his holy symbol glows the color of the sky after the sun has set - a twilight blue - and a sacred flame surrounds the officer.

// DEX 13 Save or 8 radiant damage. 

Dex Save: 10

The blue flame cascades over the officer, who howls in pain inside Roland’s mouth. He is still struggling inside the hippo’s maw!

Roland pulls out his glaive and whacks the militia leader with the backside of his glaive in the ribs, dealing non-lethal damage and then, with the same intent of knocking out rather than killing, a swift hit on the back of the knee with the other end of the polearm. 

Glaive: Attack: 8 Damage: 10
Polearm Master, bonus attack: Attack: 4 Damage: 3

The officer manages to catch Roland’s wrists as he swings his glaive, stopping the attack.
With his other free arm, he draws his saber and rams its butt into Roland’s stomach, Attack: 19 Damage: 6 slashing damage. However, Roland’s tough abdominal muscles stop the blow. He slams it again, Attack: 15 Damage: 5 slashing damage. Finally, he releases Roland’s hand and pulls a combat knife from his boot and drives it into Roland’s leg, Attack: 19 Damage: 5 piercing damage.
However, Roland barely manages to catch it on his armor! 

Penny yips at the wounds inflicted on The Hippo, and draws her short stabbing sword, whacking at the part of the officer that she can see with the flat.

Attack (with Sneak Attack for enemy within 5 ft.): 11 to hit, for 10 non-lethal damage.

Unfortunately, with Roland swinging him about like that, there’s not much you can beat senseless!

Deshi walks over to the guard and unstoppers the decanter, this time placing him between themselves and the rear door. They call a geyser once again, hoping to do as little damage as possible while forcing him out of the car. 

(DC 13 str; 3 bludgeoning damage)

The spray lets loose once more, Dex Save: 9, and while he is sprayed once more, he remains standing!

Meanwhile, the other guard swings toward Roland once more, intent on getting his commander free from the massive hippo! Attack: 20 Damage: 8 piercing damage. With that, Roland’s eyes go blank as he collapses over, releasing the other guard from his jaws.

"Dammit!" Ormond curses.

Ormond runs up to the officer and attempts to grapple him and drag him to the closest window... 

// Athletics 10

He then shouts at Roland a healing word (4 hp), "Up! Get up you undersized hippo and help me eject this officer from the train!" 

Given that he cannot beat that, the officer (who Ormond recognizes as a Vice Officer, the same rank that he himself held) is grappled by Ormond! He then drags him near the window.

Roland, once again tries to smack the badge militiaman with the flat of his blade and the butt of his glaive. 
Main attack: Attack: 11 Damage: 10
Bonus attack: Attack: 20 Damage: 3

He also gets back up on his feet before this, of course.

While the Vice Officer dodges the blade, the wind is knocked out of him by the butt of Roland’s glaive!

However, he is next to act!

He spits some blood into Roland’s face, before struggling to look at Ormond behind him, “You have some nerve turning the government, Vice Officer Sacker! Even though I’ve only heard of you, I know your type! You’re a traitor, a coward!”

He’s going to swing around the butt of his sword into Ormond’s stomach, Attack: 20 Damage: 9 slashing damage. However, Ormond’s got him tight! He tries again, Attack: 22 Damage: 9 slashing damage. The full nelson shows no mercy! With his last action, he whips the knife toward Roland, Attack: 13 Damage: 7 piercing damage!

Penny is not pleased with how this is going. She backs up a couple of seats (towards aft) drops her short sword and unlimbers her short bow. She draws on Vice Officer Badges and lets loose!

Move: 10’ aft

Action: shoot with shortbow at the officer, who is engaged with Ormond, so Sneak Attack qualified: 12 to hit, for 5 piercing damage 

Seeing that their adventure has gone horribly awry, Deshi attempts to scare away the younger guard from the fight. They speak the name of the commonroom fire from their  dormitory, which springs from their memory into being quite a lot closer to the guard than the wizard intended. 

hotfoot! DC 13 dex

DEX Save: 4

For a total of 7 fire damage, Deshi ignites a massive indoor fire under the guard. While it does not ignite the wet floor, the cloth seats next to the flame are now on fire. This is fine.

With that, the guard gets out of the way of the flame. However, he can’t actually move toward anyone, due to the fire. He could throw his sword, but he kinda needs that. Best he just hold for now.

Ormond looks down at the prone body of Roland, and mutters, "That's what he gets for not listening to me..." 

Ormond drops his warhammer and it drops giving off a heavy thud. With his now free hand he opens the latch on the window. He then whispers into the ear of the officer, "You don't know anything about me."

Ormond then shouts, "Up and out!" and suplexes the officer out the window.
