Well I came across a interesting video on youtube:

I dont know guys, what do you think? Is this just speculation? because sunrise has a bad track record at spoiling stuff in their opening themes. Iv also always thought that Marina was more of a "Onee-san" to Setsuna then anything, but then again there has been little interaction between him and Feldt from both seasons. And also theres the age difference, I know age probably doesnt matter THAT much in this series, but it CAN be a factor and it seems to me that Feldt is the only one within a reasonable age range near Setsuna. I know many of you dont care for the love side of gundam, but I just couldnt help but posting this, it might be nothing at all, anyway discuss....
