'Agents of SHIELD' season 4 spoilers: show cast for Aida, the 'very attractive' robot

There's a lot that fans should look forward to when "Agents of S.H.I.E.L.D." season four premieres as it has been confirmed that the show is going robotic since it is now on the lookout for someone who can play the role of Aida.
Who is Aida? The name sounds a bit like that of a boring character who may not really be a member of the core cast. However, there's something special about her. According to TV Line, Aida is a "very attractive" robot that appears like a normal human who walks about and does daily activities.
While Aida may walk about and move naturally, her speech is similar to Iron Man's Jarvis, who may sometimes be too formal when speaking. This makes Aida a really good catch and a very fun addition to the cast.
Two other characters are also about to be added to "Agents of S.H.I.E.L.D." season four. It is unclear which actors have been tapped for the roles but the two new characters are Latino brothers. One of the brothers is a very dangerous man who may or may not be a villain, while the other sibling is a mystery as he sits on his wheelchair, paralyzed.
Meanwhile, fans are continuously looking for hints about the plot of the upcoming installment. Screen Rant notes that production has been urging its fans to keep thinking about the possible storylines that the new episodes will bring.
One of the things expected of season four is its continuous path towards a little bit more of Marvel's darker side. Though ABC is said to not allow something as dark as "Daredevil," the previous seasons have proven to at least integrate a shade of darkness.
This could mean that the plot for the new installment will see more serious topics and matters that the agents will have to deal with. There could also be some more emotional scenes and even a potential entry of deeper romantic storylines, minus the Rated R sequences.
"Agents of S.H.I.E.L.D." season four is slated for premiere on September 20, 2016 on ABC.
