Surely I wasnt the only one thinking that a quick called to apparent Ollie BFF John Constantine would solve all of Theas problems, right? Oliver himself brings up the example of how the resurrected Sara Lance was able to live a normal life after taking a dip in the Lazarus Pit. This, as explained by Malcolm Merlyn, was down to Constantine basically saving Saras soul. So, if thats the case, and being that we know Ollie has Hellblazers number stored in his phone, couldnt the demise of Thea just be stopped by a quick call to everyones favourite chain-smoking occult detective?
