metapuzzles - The Data So Far

_{Part of the Fortnightly Topic Challenge #35: Restricted Title 1}

---

If you've been following this xkcd series of puzzles, you know that 11 of the 13 subpuzzles have been solved so far.

Your final answer is one of the panels from an xkcd comic.

Answer

The answers to the 13 puzzles are, in order of puzzle posted:

Consecutive Vowels: I WANT TO BE TOUCHING YOU
Chess Enlightenment: KNIGHT TO BE ONE WITH NATURE
Island (sketch): EXILE
Labyrinth Puzzle: MIDNIGHT
No Pun Intended: SUPERINTENDING
Listen to Yourself: EUREKA
Real Programmers: SPACETIME
Arsenic Based Life: AS YOU LIKE IT
Iambic Pentameter: PROSTHETIC FEET
Self-Description: THIS TEXT IS THE ANSWER

Five-Minute Comics: Part 1: UMMM SOME CREATIVE PUN OR SOMETHING
I Don't Want Directions: LOST FOREWORDS
Five-Minute Comics: Part 2: MATRIX FIGURE

The meta connection is:

Each answer contains exactly one occurrence of one of the letters X, K, C, or D. Each instance appears at a unique place in the answer, from 1st to 13th. (That is, for one answer the XKCD letter is first; for another answer, it's second; and so on.) This provides an ordering for the answers.

Using this to extract an answer:

In this order, the answers are:
. K N IGHTTOBEONEWITHNATURE
.E X I LE
.MI D N IGHT
.SPA C E TIME
.EURE K A
.MATRI X F IGURE
.THISTE X T ISTHEANSWER
.ASYOULI K E IT
.UMMMSOME C R EATIVEPUNORSOMETHING

.PROSTHETI C F EET
.SUPERINTEN D I NG
.LOSTFOREWOR D S
.IWANTTOBETOU C H INGYOU
The letters after the XKCD letters spell the message "NINEAFTERFISH".
"NINE AFTER FISH" indicates that we should start at the XKCD comic titled Fish, which is #1377, and then go nine comics forward to #1386.
The final answer is then a panel from this comic.

Final answer panel:

Since OP is a nice person who wants to reward their solvers, I expect this is the final answer:
