Grim watches Bow and Syvis with furrowed brow. "Not my area of knowledge, but I'll try the teeth" he says "perhaps with Petcan's help".

Grim Survival if Petcan can help: 10 Grim Survival alone: 16

Randall:

"Shall we ride ahead and make sure the bridge is safe, perhaps scout it out for sabotage or a choke point defense once the refugees are crossed?" asks Randall.

“If I were a bunch of evil goblins... I’d send scouts to ambush everyone on the bridge. We’d best go check it.” 

"Yeah lets move ahead"

"I agree" Grim says

"Orcs." Syvis hissed at the sight of the giant monster ahead of them, he moves to the side for some cover.

Attack: 27 Damage: 12 

Attack: 19 Damage: 14 

Favored Foe (add to the first one that hits): 2 

Petcan holds his hand up near his face and blows as he casts faerie fire on the Orc and his two heads DC 14 Dex save

“Welp. That thing’s ugly. Let’s shoot it.”

Attack: 17 Damage: 10

Edit: Advantage thanks to Petcan; reroll attack- 22

BA to bardically inspire people with a short haiku;

That thing is ugly

Two ugly heads, kill it

Kill it right now please

Grim attacks with Divine Smite: 17 Damage: 8 Radiant: 7

"Of course they have a giant orc"

Bow says before firing of two quick shots

Attack: 21 Damage: 20

Attack: 12 Damage: 19

bardic inspiration to second attack: 4

“Huh. That was easier than normal. I mean, that was too easy, right?”

Petcan scratches his arm nervously. “He wasn’t like a... like a legitimate guardian was he? Do you think?”

Randall:

I’m sure they would have hit very hard if we had given them a chance,” responds Randall, “but your point is well-taken.  Let us move ahead and check the body for treasure or information, then scout the bridge thoroughly before the refugees get here.”

Remember that Grimm, Randall, and Petcan still have Inspiration, might be helpful for Perception and such.

Grim considers the Ettin's words and actions, he searches the body and the immediate area attempting to get some sort of insight into the creature and it's possible motives and possibly understand why it was so easy to kill.

Grim Insight: 14 Inspiration: 3

Randall:

Randall moves forward and inspects the bridge, attempting to ensure there are no traps or other nasty surprises for the refugees to encounter.

Perception:  19

Randall:

”Let’s scout out the other side of the bridge, then come back here and keep watch while the refugees cross over.  Anyone have any ideas about dropping the bridge behind us, or maybe using it as a choke point to slow down the goblins?” asks Randall.

If the others are amenable, he rides across the bridge to scout out the other side.

Grim follows Randall over the bridge, keeping an eye out for anything suspicious.

Grim Perception: 21

"Ye, let's check the other side as well. Afterwards; it is a wooden bridge so we could see if we can set it on fire?"

“Maybe. If the city has troops, the bridge might actually be a blessing. It could thin the goblin horde to a manageable number, stringing them out as they try to cross. If the bridge is gone, it’ll slow them down, but not reduce the horde’s size on this side once they do cross. Not to say I’m opposed, just offering ideas.”
