The return of Phillip (Jefferson White) is causing quite a stir on ABC's "How to Get Away With Murder." The cousin of Caleb (Kendrick Sampson) and Catherine (Amy Okuda) Hapstall quickly became the prime suspect in the murder of his aunt and uncle early in Season 2 — but he's not through yet.

According to the synopsis for episode 14, authorities will be on the lookout for the potential serial killer, last seen inside Wes' (Alfred Enoch) apartment with Annalise (Viola Davis). While the search heats up, Caleb goes missing — could Phillip be involved? Meanwhile, the Keating Five will be called in for questioning by ADA Denver, who was given the computer containing Phillip's blackmail emails and incriminating videos. The network also teases more flashbacks, which will clue viewers in to what Annalise did that endangered Wes and cost his mother her life. 

The promotional video for the episode provides even more insight to the episode. Amid the chaos Phillip has created, there will be sex and, of course, plenty of scandal. The voiceover on the short clip suggests the episode will contain the "wildest hookup" in "HTGAWM" history — could it be Bonnie (Liza Weil) and Frank (Charlie Webber)? In addition to a shocking new romance, "There's My Baby" will reveal once and for all what happened to Annalise's son. The clip teases a flashback to the child's birth, as well as a scene in which Bonnie questions Annalise about her loyalty to Wes.

"Who is he, Annalise?" She asks sternly.

When the show left off in "Something Bad Happened," Annalise popped over to Wes' apartment to finally open up to him about her relationship with his mother. She believes he's home because of a light on inside the apartment and speaks to him through a door for several minutes. During that time she has a flashback to the moment Wes' mother died. A younger, and very pregnant Annalise, was shown talking to her client, warning her that Wes' — or should we say Christoph's — life is in danger. His mother panics and asks Annalise to promise to care for him before thrusting a knife into her own neck. Annalise begins to dial 911, but does not complete the call. She decides in the present day that she cannot allow Wes to meet the same fate as his mother and enters the apartment. Annalise snoops around for a bit, but is interrupted by a call from Eve (Famke Janssen), alerting her that she's been confronted by Wes at her apartment. Annalise realizes that something's not right and shouts for Eve to call 911 as "someone's in Wes' apartment." She is then attacked by Phillip before the episode comes to a close.
