Note: I wrote this before watching the second part of season 1 of Flash (actually still haven't watched it). You can notice that because of Iris' job.
A different kind of feeling
Once Laurel was recovered and could open her mouth without breaking all the glasses close to her, Barry took her out to meet central city and spend some time out of her room in Star Labs. And that included the bar Iris worked at. They were almost always there, actually. But that wasn't weird, he took his friends there all the time… Iris could tell this one was different, though. The way he looked at her had nothing to do with the way he looked at Felicity or Linda. It actually reminded her of the way he looked at her. That "I love you but you're my best friend and I'm afraid but GOSH HOW MUCH I LOVE YOU" look.
Why did that bother her? Maybe she just missed him… He had disappeared for a month since that night that Felicity called him and he didn't even say he had to leave. And then, everytime she had seen him, Laurel was around, and he was always sitting by her side. Was she jealous? She liked Laurel, she was amazing, intelligent, beautiful. She understood why Barry liked her so much. And she wanted him to be happy. Also she was dating Eddie. She wasn't supposed to be jealous!
But she couldn't help it. She missed seeing him laugh with her the way he was laughing when she saw him tickle Laurel. She missed going everywhere with him, and doing everything together, like they had done since they where seven. Ugh,stupid feelings. Why couldn't she just admit she loved him back?
