The next all-new episode of "Arrow" will be intense when Oliver has an awkward run in with Ted "Wildcat" Grant, and Roy struggles with the nightmare about killing Sara.

Last week, the show took an in-depth look into Felicity's life before she joined Team Arrow when her mother, Donna, made an unannounced visit to Starling City and her ex-boyfriend used a super virus to shut the city down, reports TVLine.

Meanwhile, Laurel Lance continued to train with Ted, while Roy had a vivid dream about the night he murdered Sara.

During the next episode, "Guilty," Laurel will come to Ted's defense when he becomes the suspect of a brutal murder. As a result, she and Oliver will bump heads.

A preview clip shows that Oliver and Ted will meet when Oliver discovers the body of a murder victim hanging upside down in Ted's gym. However, in order to convince the Green Arrow of his innocence, Ted will confess that he, too, used to be a vigilante.

In addition, Roy will open up to Felicity about his nightmares of killing Sara. Plus, Oliver will give Laurel a stern warning about getting involved in avenging her sister's death.

According to Carter Matt, the official synopsis reads as follows:

"After a body is found strung up in the Wildcat gym, Ted Grant (J.R. Ramirez) becomes the main suspect. Oliver (Stephen Amell) and Laurel (Katie Cassidy) argue over Ted's innocence. Meanwhile, in flashbacks, when Maseo (Karl Yune) needs Oliver to remember where an informant for China White stashed key information, he asks Tatsu (guest star Rila Fukushima) to help jog Oliver's memory. Roy (Colton Haynes) shares a secret with Felicity (Emily Bett Rickards)."

"Arrow" Season 3, Episode 5, "Guilty," airs on Wednesday, Nov. 12, at 8 p.m. ET on The CW.
