Yes exactly this, at different times of our life we are different from what we were before. I remember the episode when Miguel departed to go to Texas after Kevin was abysmally unkind, he couldn’t explain to Rebecca why he was going. One of the siblings (can’t remember which one) reported later that day “that she’s still up in her bedroom, where she’s been crying all day”. So yes, a second great love, whatever anyone else may think Miguel loved her, possibly the only person in his whole life he did love who loved him in return.
