No...because he first gave it to her (LA Proposal) and then to Lindsey (which was a kinda forced proposal anyway) and well..I mean Peyton was never insecure about Lucas's love to her and it's pretty selfexplanatory why she would want Keith's ring! It mean so much more to Luke! and as he said "Now it's right where it belongs!!"

of course not, it was her ring to begin with, plus she knew how much that ring means to lucas and to her too.

No because...
1.)It was going to be hers anyway
2.)I always had a feeling that whoever Lucas chooses would get Keith's ring
3.)When he gave it to Lindsey, it didn't seem like it ment as much as it did with Peyton

Yes because...
1.)He had given that to someone else already

it was kinda hers first! ^ same really!

No because that's the type of person she is...it didn't bother her that Lindsey had also had the ring because she knows that her and Luke are meant to be and that Luke loves her more than anything - she's completely content and confident in their relationship so why should it bother her if Lindsey has also had the ring?

What matters is that the ring means alot to Luke so by extension it means alot to Peyton.
