Really great post, I agree. I've been saying this as well, that same Starco that happened back in season 1 when things were pure and innocent, that's gone now. Battles leave wounds that heal over time, but the scars remain. Just like a brand new and sharp knife, it's most beautiful in it's early years. With time it will get dull and even if you sharpen it, it chips away and loses it's majestic form that it once had.
The same is happening to Starco, if you asked me back in S1, I would tell you "cute and perfect". But now, I feel like that happy "King Marco and Queen Star" ending, it lost the "cute and perfect".
