"Teddy Perkins" is the real Benny Hope
The man in the wheelchair is his father. With Teddy's unstable mind state causing him to go as far as to murder his own brother, it wouldn't be a surprise if he was having serious delusions in addition to murderous rage. Since his father's abusive actions created the celebrity of Benny Hope, Teddy/Benny could have had a breakdown, placing his old persona of Benny into the man who made him that way. Additionally, it seems unlikely that someone suffering from photosensitivity would be confined to a wheelchair, but elderly people, like Beny's father would be, often need a wheelchair to move around. Darius is a time traveller.
His deja vu in the pilot episode is a huge hint towards this. Additionally, he makes a lot of comments about time not being linear, such as the "we always met" line from "Alligator Man." His support of the Bostrom simulation argument is another nod towards this.- In the pilot he asks Earn's dad if he can measure a tree in the front yard, and gets turned down. While it seems like Darius just being his random self, later we hear a news report that the tree fell into some power lines and caused a blackout. It's very possible Darius already knew and was trying to prevent it.
- Shockingly, possibly confirmed in the final episode, which reveals that Darius can relive and travels through experiences (in a manner of speaking) while in a sensory deprivation tank.

"Woods" takes place on the anniversary of the death of Alfred's mother.
This would explain the dream/hallucination he has about his mom at the start of the episode. Also, throughout the day he is contacted by different people asking him how he is, starting with Earn. Lastly, the episode is dedicated to the late Willow Dean Kearse, Brian Tyree Henry's mother, who passed in May 2016.- Confirmed.
The homeless man from "Woods" was a figment of Alfred's imagination.
At the end of the episode, Al is humming the same song that the homeless man was humming in the woods. His cryptic dialogue is also a hint towards this.
