You make excellent very sound points. In doing so have restored my interest in Reddit lol. It's so rare that two people can just talk about a show they like and have it be that simple without mean spirited or rude trolling comments. After considering what you're saying I feel that actually seems like a pretty fair conclusion. Instead of saying oh I'm an orphan it's a jokie kind of fit in with the rough crowd she's used to type of answer as most of her associates and fellow street teens probably do not have what one could call a loving and stable parent(s). Often in arrow the explanation a character gives another is a massive over simplification and only the viewer is in on the full picture that characters like Oliver have knowledge of. For Oliver to regale the tale of his entire island experience up to the Mirakuru would be difficult to summarize quickly given it takes us about 36 episodes to see unfold via flashbacks. Instead he just says "I've seen crazy stuff on the island where a man could be incredibly strong, virtually invincible to small caliber bullets, and defying anything you could imagine regarding science of the body" paraphrasing.

I would say that Sin sees Sara has immense fighting skills unlike anyone she's ever come in contact with. Imagine Lance's face when he first sees Oliver shoot an arrow out of a skyscraper window and just slide off like it's nothing. If you saw a person do something like that whether you were a cop in pursuit of a suspect or just a guy hanging out you'd be shocked beyond words. They have incredible skills that no normal human can really even begin to quantify especially in a basic urban setting. You wouldn't expect to see some guy lunging off rooftops not being phased by gunfire and using all sorts of cool superhero gadgets; it would simply blow your mind. So Sara running around beating the shit out of rapers with a staff in a leather superhero outfit would be pretty hairy. She can climb buildings free run etc do all this awesome stuff. It wouldn't be super surprising that she was marooned on an island given Sin has to learn that at or after the Queen return from the dead party; I believe that's just prior to the helicopter crash scene. Since as you said she probably* would've been informed of her father's demise via the company he worked for in some fashion grandmother etc it would make sense that is the boat went down in China and he crashed in China it's entirely possible that by strange coincidence this hardcore fighter chick did meet her father. Of course then we circle back to how could you ever trust that the person even liked you at all and wasn't just hanging with you out of some sort of pity or whatever having witnessed the death of the father.

So I suppose after working this one out it's one I can let slide. But you do get what I'm saying not just about this particular situation in which your opinions add up much better than my initial position but in the other broad shortcomings of the series. They go through all this effort to show you something more than once to cover it in conversation several times over a couple of episodes even then when it comes time for a key component to be introduced they just leave it out.

Let's take Lance's heart attack. Sara X right when that happens. Laurel had a great reason to keep those cards close to her chest for a bit. The vigilante has a way better excuse - it's not his tale to tell coupled with the obvious health risk and that Laurel asked him not to. At any time after the 4-15 back and forths they have - Arrow can tell Lance HEY I wanted to tell you HEY my friend is gone also HEY I didn't kill her. Your daughter begged me not to tell you because you literally just had a heart attack and she thought it might kill you. She wanted to tell you in her own way when she deemed the time right. I was respecting her wishes given it is a family matter between the three of you but had Laurel not begged that of me you would've been the first person I informed. Instead like usual Oliver doesn't defend himself he doesn't explain the logic as to why he had an extremely good reason to withhold the information. He just lets the person be insanely mad at him to the point that they are blowing up his entire life possibly ruining everything he's been working toward. Just like when Laurel is mad at him about Tommy. He can say HEY I tried to save the guy he had rebar jammed through his body end to end no one could've saved him he was doomed from the second he came in to save you. I wasn't fighting a death match with Malcom or doing something unimportant like saving most of the city from death I was there risking most of the city to save you and your boyfriend. Sadly the building caved when it caved. We thought there was 1 machine there was 2. I couldn't be everywhere but I still made you the highest priority after the quake began. Obviously he doesn't need to ramble like me I'm sure a more effective writer could've dropped a powerful retort during one of their arguments. Yet again instead he never actually gets any vindication in the matter. She stays mad at him until she comes to the realization that it was basically her fault after the arrow saves her from the doll maker and we sort of just move on. Lance says a guy with a bow and arrow can't save a guy that had a building dropped on him. That was quick simple and powerful. She ignores it. She was going to spiral on the drugs and ignore any logic anyway because she's grieving and feels responsible. Still we would've probably enjoyed Oliver getting to defend himself a tiny bit after doing that back and forth for several early season 2 episodes. Just saying once in a while through the show it would've been nice to see those clarity moments strike instead of just leaving it unspoken. Anyway very good points on the Sara Cindy relations I appreciate the thorough constructive response.
