A common theory/hope that I see around the web is the hope that either Tommy or Sara (who literally just died) will return.
Personally I wouldn’t mind if they returned, I would much prefer that they stay dead. Not only have their/will their deaths pushed for HUGE character evolutions, but those evolutions wouldn’t be slightly negated by their returns. i.e. Laurel’s evolution into (Black) Canary, Oliver’s no kill rule, Oliver’s emotional change, etc. Although arguably their respective returns could bring on more change, it brings more harm then its worth (see below).
On top of this, the largest complaint about Marvel’s MCU is that characters don’t stay dead, and that detracts from the movies: Nick Fury, Loki, Coulson, and now recent theories/rumors that state Thor could die in Age of Ultron and wake up in Hel (one of the 9 realms). Lastly, Arrow seems to really be pushing for more comic characters who have backstory. Although Diggle and Felicity seem to fall into that bracket, they have recently been introduced, so their backstories (comic-wise) can still grow. Stay tuned for my predictions as to what will come in the future for them. Debatably, Sara is a take on Dinah Laurel Lance, in the sense that she was the first Canary, and has now passé on the mantle to Laurel, as Laurel’s mother typically does (that would be really strange on the show…Mrs. Lance/Drake in the Canary costume fighting crime). So this is my initial reasoning…And arguably Tommy has been introduced in the New 52...but his role is very very minor as of now and has yet to be touched on for quite awhile. However, taking that point into consideration or not, here are my further thoughts on the matter...

|Yea! ... No...|
However there are a few general flaws with this hope, the first being the time Tommy has been dead. Off the top of my head, there is a limit to the Lazarus Pit’s use… you can’t toss a skeleton in there and assume it will return a fully fleshed human, it has its threshold of use.

The third large issue with Tommy's return is coincidence (for lack of better word)... why...of all characters are the Merlyn's the ones who are returning? That seems all to convent and coincidental, harkening back to the point about keeping more comic based characters around... they should go ahead and kill one of them off just to bring them back eventually... but not this Merlyn...nor the following Lance.

A few fan theories include Sara returning via Lazarus Pit based on Nyssa's love for her and the New 52 Futures End incarnation of Black Canary who runs the

Many of the Tommy theories apply to Sara as well and vice versa...here is the final theory from fans which...I will simply allow the picture to explain. However, this won't be happening...we don't even have GL yet...and no...Diggle will not be GL...click here to take a look at that...

In the end...people only want them back because they are fan-favorites...when Oliver gets a new buddy (or Roy grows into the role) and when Laurel becomes Black Canary...and everyone likes her we will forget about these two.
