Travel Back in Quine The challenge here is simple, and not at all about byte-count. Your job is to output the first 50 characters of the previous quine's source code, concatenated with the first 50 characters of yours starting with the 50 characters I've placed below:
abcdefghijklmnopqrstuvwxyzACDEFGHIJKLMNOPQRSTUVWXY

So, lets take an example here, if you were to answer in 05AB1E, a solution to simply output the first 50 bytes would be:
ži50£

Which would mean you'd need to output:
abcdefghijklmnopqrstuvwxyzACDEFGHIJKLMNOPQRSTUVWXYži50£

If your program is shorter, simply use the first x &lt; 50 characters. If your program is longer only concatenate the first 50 characters, ending on the 50th character. The next person will then have to output the first 50 characters of your quine concatenated with their own code.
Your code can be any size, but you should only output the first 50 characters of your code concatenated to the end of the first 50-bytes of the previous answer's code.

Restrictions:
This uses the definition of a proper quine, and, in addition to this, the following things:

Comments are disallowed, entirely.

How to Post a Chained-Answer:

Post a placeholder:

Mention your answer number and the language you'll use.


Sort-by-date, if you notice someone else posted a placeholder 1 millisecond before you:

Delete yours, wait for the next opportunity, sorry.


If you've secured the next spot, PLEASE ANSWER WITHIN 6 HOURS:

If you can't answer, remove your reserved space.


IF the space has been hogged for more than 6 hours.

Vote to delete reserved space, I'll handle it.




Your Post Format:
#[Answer #]:[Character Count] Characters, [Language Used]

Some specific notes (Important for Ease-of-Competition):

If the person before you has included newlines or non-ASCII characters in their source, you may STRIP them. This means that x=&quot;a\nb&quot; becomes ab, where x[0]=a;x[1]=b;.

You must state the mutation you've applied to the previous source.


All characters are counted as a single character, despite code-pages or language encoding. Please do not use byte-count, use character-count.


The accepted answer will be the 50th answer, just because; I mean, it's SE afterall.
1: 96 Characters, Haskell

abcdefghijklmnopqrstuvwxyzACDEFGHIJKLMNOPQRSTUVWXY:z=['`'..'z']++'A':['C'..'Y']
main=putStr$z++z

Try it online!

I was feeling silly, and saw nothing forbidding the first entry starting with the exact same 50 characters as the initial string.

['`'..'z']++'A':['C'..'Y'] is an expression evaluating to the string of those characters, with a ` prepended.
The result is pattern matched on,
making the variable abcdefghijklmnopqrstuvwxyzACDEFGHIJKLMNOPQRSTUVWXY equal to '`', and z equal to the 50 characters.
main=putStr$z+z then does the actual output.
