Need to ADD missing hyphen on second line when hyphen only exists on first line only:

24
00:03:01,848 --> 00:03:04,893
- How adorable.
[both laughing]

48
00:02:53,798 --> 00:02:54,758
[clears throat]

49
00:02:57,552 --> 00:02:59,971
- [clears throat] Phil.
What can I get you?

168
00:07:01,421 --> 00:07:03,048
Really?
- If that's possible, yeah.

169
00:07:03,089 --> 00:07:04,007
- Really?
- Mm-hmm.

Here's what I thought might work [no cigar]:

Find:       ^([- ])(?=.*\r?\n([A-Za-z\[]))
Replace:    - $1

The CORRECT end results would be as follows with both lines having hyphens:

24
00:03:01,848 --> 00:03:04,893
- How adorable.
- [both laughing]

48
00:02:53,798 --> 00:02:54,758
[clears throat]

49
00:02:57,552 --> 00:02:59,971
- [clears throat] Phil.
- What can I get you?

Thanks in Advance, Hank

You want to match a line that starts with a - followed by a line that doesn't start with -. Use a negative lookahead to implement the "doesn't start with" criteria.

Then you want to add a - to the end of whatever this matched.

Find: ^-.*$\r?\n(?!- )(?=.) Replace: $0-

Try (regex101):

^(-\s+.*?)^([^-])

with flags MULTILINE and SINGLELINE. Substitution is string:

$1- $2
