Interactions with Barry AllenEdit
After Barry Allen and an intoxicated Caitlin Snow performed a duet at a bar, Linda Park complimented Barry's singing. She then gave Barry her number and told him he could do what he wished with her number. Later on, she was picked up by Barry Allen at the Central City Picture News headquarters for a lunch date. Afterwards, they went on another date for spicy tacos, which Barry has little tolerance for. On their third date, Linda cancelled Barry's plans to go out in favor of simply making out with him in his living room. However, Barry was called away to perform some duties as The Flash. Linda, unaware of this, believing he still harbored feelings for Iris, decided to end things, only for Barry to prove his worth by threatening to eat a very spicy pepper (referencing to their second date) if she didn't agree to go out with him.
Linda is shown to have an outgoing personality. She's also very fast in relationships and dating as she was already making out with Barry on their second date when Berry had made plans for them to go out.
The two Parks Edit
Linda Park was originally simply an Easter egg in the Arrow episode, "Three Ghosts".
Played by Olivia Cheng, she was seen on Barry Allen's Central City Police Department laboratory television, reporting on the S.T.A.R. Labs particle accelerator disaster. Since that scene was crucial to the plot of The Flash pilot, Cheng's Arrow scenes were reprised in that initial episode of The Flash. Technically, then, Cheng never filmed scenes specifically for The Flash.
As the first season of The Flash progressed, the producers decided to bring back the character as the fourth leg of the "love rectangle" also involving Barry, Iris and Eddie. This time, the character wasn't a television reporter, but instead a print sports reporter.
According to actor Malese Jow in a February 2015 interview, the casting and character change was something "we don't really clarify". And because Cheng was really "the Arrow Park", Jow correctly implied that her version of the character was "The Flash Park".
