I don't wish to get into your discussion, though i obviously agree with you lol, CindyxJeremy is never happening, cindy is too confident in herself to let someone else corrupt her.
Anyway, There is a possibility for them to be friends in my opinion, idk if you remember us talking about this a while back, Ian & Lena being in a relationship and wadeXcindy points atleast 2. Ian would save their relationship and later maybe the 4 of them can go on a double date or something where Lena & Cindy connect on a more personal level and talk things out, they never even had a single situation where they talked with each other for even 1 minute. In my opinion Ian would be the catalyst for them to become friends, since cindy is going to appreciate him a lot when he saves her relationship with wade
