Need to REMOVE hyphen when only on SINGLE line between time codes. So in the case below only want to remove the hyphen on #24. FYI: The line could end many different chars.
19
00:07:03,089 --> 00:07:04,007
- Really?
- Mm-hmm.
24
00:03:01,848 --> 00:03:04,893
- How adorable.
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?
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 hyphen removed on #24

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

00:03:01,848 --> 00:03:04,893

Thanks in Advance, Hank
You can use a negative lookahead pattern to match the line before a line that starts with a hyphen and is not followed by another line that starts with a hyphen, capture the line and include the hyphen in the match, and substitute the match with what's captured but without the hyphen:
Substitute:
^((?!- )[^\n]*\n)- (?![^\n]*\n- )
with:
$1
