The way this series has treated Elena is so sad its funny
So first, she comes in as this shining light in Fast Five, the one cop in Cuba not on a drug lords payroll. Awesome. She gets a tragic backstory, some motivation to clean up the streets, and forges a relationship with Dom on the strength of them being kindred spirits. Fast forward to Furious 6 and she
willingly lets go of the dude she's in a relationship with because his ex shows back up (she doesn't know they're married yet) and is cool with the whole thing. Dom does her dirty and it doesn't even get one ounce of dialogue as to how she's dealing or how he's dealing in a very awkward situation.
But she got her job back with Hobbs and is now working in the States. Cool, good for her
Furious 7 comes and she's a glorified secretary/babysitter, watching Hobbs' kid while he goes to be the big man on campus. She's a cop with skill and they say "yeah babysit the kid"
Now with part 8, we find out she and Dom truly did love each other, conceived a child, and she was even willing to wait till after her son's dad came back from his honeymoon with the the woman he left her for to tell him the news
And what does she get for her troubles? A bullet to the brain
God did this woman a favor by taking her our of her misery but man you talk about underserving a character and just beating them into submission
