I'm normally opposed to Lindsay/Daniel, but you made it work perfectly here! Great work!

I really enjoyed this. I wouldn't have imagined this scenario for Kim, Daniel, and Lindsey, but your characterization is right on. Thank you for sharing this.

This is one of the few F&G one-shots that really drew me in from beginning to end and I felt it was both complete and very elaborate in the length of time it covers (which always makes a story feel longer to me).

Overall, there are a few things that I am of a different opinion on, but we all have our own assumptions as far as who these characters truly are and how they develop. I will say that the opening provided great insight with your description of Lindsay and Daniel's relationship and the closing to it ("As long as she was friends with the freaks, she would always have secrets") was amazingly simple, accurate and something I had never really thought of before.
The Jerry Garcia thing was a humorous shock that I did not see coming at all (kudos on that, haha).
I will fully admit that I am a tad confused as to the timeline of your piece (not sure if it is supposed to be AU or 1982 when both Kim and Lindsay would be entering their senior year. 1982 would mean Kim decided to follow the dead for the summer again, as she already did it for summer of 1981 with Linds, Victor and Laurie (though that would be perfectly understandable if she liked it)).
There are a few spelling and punctuation errors here and there (I can send you a PM with them if you want), but nothing truly distracting. Actually, even with the few bumps I did run into, nothing was truly distracting from the story you told. It flowed very well and the situations and characters (for the most part) were very authentic. I liked this a lot, and I really wasn't sure f I would at first (mainly because a lot of Lindsay/Daniel tales seem to rush into the relationship part and alter the characters in the process).
Having the bond start with James as the connecting point was interesting and proved to be a very strong choice to go with. You could see the relationship grow just as the baby did.
I have a slightly different outlook on the tug of war analogy. I don't think Kim gave up. If Lindsay truly is the white flag in the middle of the rope then Kim is still pulling strong by not only depending on Lindsay to take her place, but also to keep holding the spot indefinitely. In that situation, Kim needs Lindsay just as much as Daniel does so she can go on living her life with the knowledge that her son is safe and secure with her friend.
