Print the previous answer in reverse - with a catch (pt. 2) Your challenge is very simple: output the previous answer, in reverse.
However, as with this similarly-titled question, there's a catch: in this case, you cannot use characters from the answer before the last. For example:
Let's say the first answer looks like this:

1 - Python
print('hi!')

And the second answer looks like this: (see 'Chaining' section for more info)

2 - Javascript
console.log(&quot;)'!ih'(tnirp&quot;)

Now, it would be my job to write the third answer: a program to output the text )&quot;print('hi!')&quot;(gol.elosnoc, without using the characters p, r, i, n, t, (, ', h, i, ! and ). I can choose whatever language I like to complete this task.
Chaining
The first answer can output any text: but it must output something. The second answer should simply output the first answer in reverse, using any characters you like. The further rules about restricted characters, as described above, come into play from the third answer onwards.
Scoring
Your score is \$\frac{l_{n}}{l_{n-1}} - l_{n-2}\$, where \$l_x\$ represents the length of the \$x\$th answer, and \$n\$ is the position your answer is at in the chain. (all lengths are in bytes; if your answer is no. 1 or no. 2 then miss out \$l_{n-1}\$ and/or \$l_{n-2}\$ where necessary.)
Best (lowest) score by August 1st wins.
Formatting
Please format your post like this:
[Answer Number] - [language]

    [code]
    (preferably a TIO link)

SCORE: [Submission Score]

(notes, explanations, whatever you want)

Everything in square brackets is a required argument to fill in; everything in normal brackets is an optional argument; everything not in brackets is there to make the snippet work.
Rules

All characters, etc. are case sensitive.
Preceeding/trailing whitespace is allowed, within reason (I'm looking at you, Whitespace).
Every submission must be a unique language.
You must wait at least 1 hour before submitting a new answer if you have just posted.
You may NOT submit two answers in a row, you must wait for TWO more submissions before posting a new answer.
Of course, standard loopholes are disallowed.
Please make sure to triple check that your answer is valid. This is especially important, because someone may start writing their answer based on yours, so if it's wrong you can't really edit it any more... and the whole chain breaks down. Also, you can't edit answers for continuity purposes.
Standard I/O methods are allowed.
