So let’s suppose that not every happy ending is your ending up with someone, then wouldn’t it be better for Red to end up in SB rather than FTL? 1) she has skills and abilities she can use while living there 2) She wouldn’t have to remember what she is and did in FTL. Perhaps her Happily ever after is best not knowing:)
Tongue in cheek: maybe a wolf-man (shrek-like) is her true love and when he kisses her they both become wolves and live happily ever after:)
