Again, drop the loop and use a smaller hook to pull the ch back through the next set of sts. This photo is a little wrong because that pink working yarn should still be threaded through thos lifeline stitches. If you accidentally pulled it out and it looks like this photo, just get your tapestry needle and thread it through the lifeline stitches again.
Again, the pink working yarn should be in where the lifeline is and where the little hook just pulled the ch through.
This is me putting the pink back where it belongs.
I had cut out one of the dc in the next group, so I need to re-create that, then I attached it to the existing st with a slip st. You should attach it anyway you can creating the least amount of obvious join.
