There is an old fanfic (written when Unbelievable run was ending), where Gwen knows her time is running out and wants to make amends with Miles and they eventually go on a date.
The best part of the fic is a dark reference near the end:
Gwen takes Miles to white space, to show him she doesn't have much time. Miles swears to find a way to save her, and we get this gem from her - "Oh Miles... You can't save me. You're Spiderman and I'm Gwen."[/spoiler:lit]
That's pretty clever if brutal use of meta joke.
