Hey, Paulo and Nikki are awesome! But, I don't know what there realationship is...
Lovers- Nah, they argue too differently.
Friends- Hmmm, might be.
Siblings- Could be possible, and most likely to be true.
There, and shame they had to kill off Eko, I cried too much, I cried myself to sleep.
RIP: Eko, my old favorite character.
