Thea's sole purpose in life seems to be feeling aggrieved. Somebody's always lying to her about something or other and if she didn't have her righteous indignation, well, what would she have? So no, I don't expect her to get all lovey/sisterly with Ollie again now that Moria's gone. Not when there are new levels of pouty to achieve!
So, before the end of the season, I figure these things have to happen:
1) Roy's got to get de-mirakaru'd so he can become a good-guy again. My bet is he'll be commanded to kill somebody on TeamArrow and his indomitable will will finally purge his system of the mirakaru and he'll become heroic again. Maybe even a "final sacrifice" to save Thea?
2) Sara has to die heroically at Slade's hands so Laurel can pick up the booby-squeezing bodice and become the Black Canary (disclaimer: I'm not happy about this - Caity Lotz fills out that costume nicely. And I'd miss her chin dimple.)
3) Ollie's knee has to make an Adrian Peterson-like recovery so he can mix it up in hand-to-hand combat with Slade. Or, his knee will prevent him from defeating Slade on his own, leaving the possibility open for a noble, self-sacrificing act by another character. Sara? (remember, you heard if first here)
4) Slade has to die. Duh.
5) Felicity and Diggle have to look concerned at the carnage going on around them. One of them will be threatened but saved.
My big questions: Will The Flash come to Ollie's aid in the BigShowdown with Slade? 'Cause that would be cool, give a good lead-in to the new series, and give Felicity something more to do than just look worried. Will we get any more Isle o' Doom™ flashbacks? (I loves me some Island flashbacks.)
And, lest we forget, Summer Glau is still out there and has been resurrected & miracaru'd. You know she's going to figure into the FinalShowdown somehow. More Summer is always a good thing.
