... Zeke at long last recognizes the series of puns taking place before his eyes, and snorts.

He opens the leftmost door; it does not immediately erupt in fire, and the small corridor it leads to seems innocuous. 

"We await your footsteps to follow in, O great and noble drow.  Or great and brute, rather."

“Can’t wait for the character arc thingy where you, like, turn into the quippy bard you’ve always wanted to be, it’s gonna be a real thriller.”

His footsteps are thereafter followable. 

Surly gravity-toggle, for two rounds this time.  Follow follow.

Zeke fails to notice it.

The rest of the party also follows; they eventually reach another set of three doors.

Jace waits to see if Zeke picks a door without input.  When he doesn't: "Well, we've eventually been picking the right doors; let's do that one."  The door she points at is neither the left nor the center.

"That was pretty tenuous," points out Morgan in a slightly odd tone.  "We've been starting with the right doors even when they're wrong."

Jace does not gravity-toggle her for this.

“Jade and I are both very charmed by all of this wordplay.”

“Jade likes it too?”

“He likes it more than than he likes most things that he encounters? That’s admittedly still a very low bar.”

“Fair.”

He cartwheels over to the rightmost door and opens it; it declines to produce a burst of flame.

. . . Incentives.  "I continue to find you two tolerable," she says to Kamin.

“I’m glad!”

"Yeah."

A dracul, billowing cape and fangs and all, quietly drops down from the ceiling behind the door; Zeke kicks it and it makes several disturbing cracking sounds. The devil that had previously been animating it drags itself out of its chest; he smashes it against the wall and it disappears in a puff of smoke.

”Onward?”

"If you please, kind sir."

“Only two copper a bag, feed the birds, something something.”

Onward!

A decaying octopus with knives attached to four of its limbs squeezes through a tiny gap in the wall, to their rear, and slashes at Morgan. 

She dodges, grasps one of the tentacles at the base of its knife, and hefts the beast against the wall of the corridor.  A few times, if necessary.

It makes weird squelchy octopus noises and an odd cracking sound and then it stops moving.

Yay.  She's helping.  She wipes her hand off on her trousers and pops another treat from her pouch into her mouth.

The catacombs do not interfere with treat consumption; it is yummy.

They eventually reach... another set of three doors!

"Do you seriously need someone to tell you to try the right door and move leftwards if that's a bad pick every time," Jace flatly asks Zeke.  "I'm going to run out of puns.  Or do you have some reason to not want to do that."

“If I start caring less about party consensus you’re gonna hate that, I’m not, like, trying to be a super efficient person or whatever your vibe is. I can start doing it by default now that you’ve, like, mentioned that as a thing.”

He opens the rightmost door and it makes a loud, not-quite-deafening gong; the middle door doesn’t do anything in parficular, and leads to a large chamber, containing nearly a hundred doors and a large sphinx wearing a sharp suit and bowtie on their upper half.

“Answer my riddle,” booms the sphinx, “and I shall tell you which path leads to the mortal souls you seek!”

'It's not consensus when I'm the only person leading things,' Jace does not say.

'Right, I somehow forgot you don't know any psionics and expected you to pick that out of my brain instead of figuring it out from context clues,' Jace does not say.

"Ooh, a riddle," Jace says.
