Who wants to discuss the show arrow? I have so many questions.

Re: ARROW- anyone watch

some of my questions...

1. so tommy's dad is bad correct?
2. what is the deal with the island oliver was stranded on and what's the deal with the asian guy who trained him to work with the guy he is with on the island now?
3. what do you think of mckenna i think there is more to her story...
4. How would Sarah have survived?
5. Why didn't she talk to her mom/where has her mom been?

i feel like i had more questions... everything is so entwined lately, I can't keep it straight.
