Arrow S5E21

Thoughts:

• Oliver receives a package of a body encased in concrete that we later find out has Oliver's fathers DNA and connection to Queen consolidated. The flashbacks are back and so is Thea
• A connection is found and the team tracks down Adrian's fathers lawyer who gives Oliver and Thea a flash drive that shows their dad pushing the body into a vat of concrete.
• The team tracks down Samson and his team steeling chemicals and they think that he is working for Adrian to get the chemical needed to  replicate the concrete from the crate.
• In the flashbacks we find out Oliver goes back to the island and Anatoly was supposed to bribe a fishing boat to "find" Oliver in a couple days but it doesn't look like that happened.
• Again loving this relationship between Quentin and Rene and working towards getting Rene's daughter back which means testifying in front of a judge but he never shows.
• Oliver and Thea struggle with the realization that their father, parents for that matter, are not who they thought they were.
• Oliver puts the Green Arrow suit on again as he battles Adrian and the Team fights Samson and his men to prevent the chemical from being disbursed on the city.
• Oliver talks down Adrian and captures him. Oliver gives Thea the flash drive with a video from their dad for Thea that he has kept. Oliver is not alone on the Island.

Predictions:

• Oliver is going to miss his ride home and he is going to have to kill Kovar and his men to take the island. He will then be found months later.
• Adrian is going to get out of jail somehow or be transferred to the ARGUS prison on Lian-Yu to set up an epic fight on the island.
• Even though Chase is in jail his allies on the outside will still case chaos and attack members of team arrow.
