Oliver was working out in the foundry when all of a sudden Felicity came running down the stairs in a hurry.

"Oliver, we have a problem"

Oliver stilled and quickly walked over to Felicity, "What's wrong?"

"Thea"

Now Oliver was getting worried, "Thea, what's wrong with her, is she hurt?"

Felicity quickly realized what that sounded like, and tried to reassure Oliver,
"Oh no, no, nothing like that, I know that sounded cryptic, but I swear it wasn't meant to, I just meant that we have a problem with Thea. She isn't hurt or anything, it isn't a big deal, actually it kind of is a big deal, but not as big as injury or.."

"Felicity" Oliver sighed to signal to her to get back on track.

Felicity smiled sheepishly, "Yah sorry" she cleared her throat and continued, "What I was saying is that we have a problem with Thea, she thinks I'm cheating on you"

"WHAT?"

"Yeah she saw me kissing you, now she thinks I'm cheating on you"

Oliver was now completely confused, "Wait a minute, she saw you kissing me, and now she thinks you are cheating on me, what are you talking about, we're together Felicity, you are supposed to kiss me"

"No, no, you don't get it" Felicity pointed between herself and Oliver, "Thea knows we are together but she doesn't know that me and the Arrow are together too. I mean she knows I'm dating you you, but she doesn't know that I'm dating Arrow you too, so if she sees me kissing you you it's not a problem, but me kissing Arrow you is, because she doesn't know that you you is the same person as Arrow you, and she saw me kissing Arrow you which in her mind is a different person from you you, so now she thinks I'm cheating on you you with Arrow you, even though you you and arrow you are the same person. Do YOU now see what a big problem this is"

Oliver was now even more confused, "Honey, I think you lost me at the word 'you'"

Felicity sighed in frustration, "Urghhh Oliver that saw me kissing 'the Arrow' and now she thinks I'm cheating on you with the Arrow"

Now everything was finally falling into place for Oliver and before he could stop himself, he was laughing.

Felicity pouted, "We have such a big problem and you're laughing, really Oliver, god you're useless"

Felicity was about to walk away but Oliver stopped her by wrapping his arms around her waist and bring her closer to himself.

"Honey, I'm not laughing because of the problem, I'm laughing because when I started this whole arrow business, the double identity, I knew I would have a lot of problems in keeping the arrow identity secret, but never in a million years did I ever imagine that I would be in this situation where my sister would think my girlfriend is cheating on me with my alternative identity"

Felicity rested her head on his chest and let out a breath, "I know, but what are we going to do, Thea is so important to you, I remember when you first introduced me as your girlfriend, her reaction, approval, whatever you want to call it was important to you. And I was so glad that she liked me for you, you know. And now I'm just scared this is going to ruin everything, I know you know the truth but Thea doesn't, and she's become such a good friend to me, like a sister, and I don't want to lose this new family of mine."

Oliver understood, Felicity had never felt a part of a family, with her father abandoning her and her mother never acting as a mother, he know what this surrogate family meant to her.

Oliver kissed her on the top of her head, "I know felicity, and you are never going to lose me or this family. Look we'll just tell Thea that the arrow saved your life, like from a mugger or something and you just kissed him in the moment as a thank you, and I'll tell Thea that you told me about it and I'm completely fine with it because I know you love me and the kiss was just a thank you and it didn't mean anything else obviously."

Felicity pulled herself away from Oliver's chest to look him in the eye, "That's actually really good"

Oliver pretended to look offended, "Well don't look so shocked, I come up with good excuses"

Felicity rolled her eyes, " Yeah whatever you say Mr. my coffee shop is in a bad neighborhood slash I ran out of sports bottles"

Oliver laughed lightly, cupped her face and gave her a soft kiss. He then rested his forehead against hers and said, "So we good?"

Felicity lightly nodded, "But for the record I expect the arrow not to kiss me again"

Oliver smirked, "Well what if he kisses you in just our bedroom."

Felicity smirked back at him; "Well if he does that he better not stop at kissing"

Oliver leaned into kiss her again and whispered softly against her lips, "I think that can be arranged"
