RedWolf, could you post links to the references?
It is somewhere in the spoiler section.
According to the spoiler Meredith has a family member with the same power as her. Who else in the current season has a fire ability?But here's a reference in the Heroes wiki.
http://heroeswiki.com/Theory:Meredith_GordonAs for Echo bio from the tracker.
http://heroeswiki.com/EchoQUOTE
Echo DeMille has two brothers and a sister. He is the only one of the DeMille children not to serve in the military, and Echo's relationship with his father — an ex-Navy SEAL — has suffered as a consequence. Echo is closest to his sister Farah, a registered nurse.
Echo was profoundly affected when his eldest brother was killed while serving in Iraq. Later, Echo's troubled younger half-brother, Jesse, joined the military as well but was discharged during boot camp and was soon picked up the first of what would be a long series of misdemeanor and felony arrests. Echo was an early accomplice in many of Jesse's infractions but their paths diverged when Echo made his first breakthrough as a DJ.
According to an early interview with his local newspaper, Echo's self-described passion for DJing stemmed from a belief that music empowers humans on a subconscious level, increasing social potential and communication awareness. At one point, he described music as a way to hide as well as a way to get along. Apparently still unaware of his post-human abilities, Echo began to travel extensively to explore various cultures and their music traditions, and as a result, became increasingly known in club circles for both educating and entertaining his audiences through his unique, eclectic musical choices.
At the height of his success as a professional DJ, Echo announced his decision to become a mailman. He explained his choice by saying that he wanted the opportunity to serve his community and he had long admired the legendary consistency of the mail carrier to deliver "rain or shine." Shortly after joining the Postal Service, Echo's power began to manifest.
A sound manipulator, Echo can mimic and distort noise, replicate frequencies, and create sonic blasts of devastating proportions. Echo has noticed that his ability to manipulate sound increases greatly when his fight-or-flight reflex is engaged. He seems to regard his ability to manipulate sound in all its forms as both a blessing and a curse, and he actively continues to explore the extent of his power.
For the past ten years, Echo has lived in Los Angeles, a city that he calls home. He recently purchased a house with his girlfriend, Gina, using funds saved over the course of several years.
This shows that two siblings could have the same base ability. But with Nathan he wasn't born with the genetic code for abilities.
He's like Mohinder the powerless sibling of Shanti who was hinted having an ability.
Both Peter and Sylar have the capacity to use multiple abilities and being brothers support the premise that natural powered siblings has a disposition to a particular power.
When you think about it Empathy and Intuitive Aptitude are two sides of the same coin.
Empathy is about feelings while IA is about how it works. Different methods of comprehension.
I think the reason why Sylar could not access his abilities in the present as opposed to the future is that he does not understand instinctively how some of his abilities work.
As in the future Gabriel is an emotional man. So Gabriel can access his abilities like Peter can.
