Her own father didn’t want her back. Even the post-finale interviews suggest that Tommy could just hook up with her doppelgänger, no big deal.
I never liked E1 Laurel, but sometimes I feel like no one hated her, not even every person who’s ever watched Arrow and disliked her combined, more than the Arrow writers.
I wish we’d gotten flashbacks showing some of the changes (like with Tommy, Moira around) instead of the S1/William kidnapped connected plot. (And one of those could’ve maybe involved Felicity? Since they couldn’t get EBR for the flashbacks we got. Maybe they could’ve fit in a quick moment with her?)
