A bit tinfoil here, but with regards to Ruby's future and role in the plot...

My theory is Ruby and the whole Silver Eyes thing is history repeating itself cyclically. Summer also had Silver Eyes and I think Ozpin "sacrificed" her by sending her on a big mission where she was forced to use the powers to stop Salem's last plan, but at the cost of her own life. And I don't think Summer was the first one to be sacrificed in this way. Ozpin might be planning to "use" Ruby in the same way to preserve the peace of Remnant (for another 10 years before the next cycle).

We know Ozpin's not above using people for the greater good, from the way he used Pyrrha to retain the Fall Maiden powers. It also lines up with songs like "Time to Say Goodbye" ("are we weapons pointed at the enemy so someone else can claim a victory?"), "Sacrifice" ("Take the lives of those you need / Sow the death then reap the seed") and "Divide" ("Sacrifice them for your needs"). A lot of things point to Ozpin not really being benevolent as he seems, even if his intentions are ultimately good, and Ruby clearly plays a vital part in his plans. However, I think ultimately Ruby will wise up to this cyclical thing and break out, bringing a more "permanent" peace to Remnant by decisively beating Salem (and defying Ozpin's expectations in the process).

Also speaking back to the "history repeats itself" theme, I can totally see Ruby and Jaune being an echo of Taiyang's relationships. They both "lost" their first relationship (Tai because Raven ran away, Jaune because... of other reasons) and then their second relationship is with Summer/Ruby. And that's of course not counting the fact that Tai and Jaune both have similar color schemes.
