So if by end of day tomorrow the stock is over $109, then i have the option to purchase 100 shares at $109? 
  
 if i dont do that then it expires worthless? 
  
 If i hold until tomorrow and its up say $1000 and it expires, then its worth nothing?

If MBB is above $109 when your option expires, Robinhood will exercise the option for you meaning they will buy 100 shares at $109 from the option seller and sell it immediately at the market price above $109
