He is portrayed by Doug Haley.
Walter is quirky and somewhat geeky 17 year old. Not much is known about him or his personal life with the exception that he is in drama club and in Teddy's government class.
He's very tall and lanky, with brown medium length hair. Most of the time he wears skinny jeans.
