Wallace Mahoney, revealed to be Wes's dad in the finale of HTGAWM season 2, was shot dead immediately after Wes confronted him, but details about the character will be divulged when the series returns.
Pete Nowalk, executive producer of the ABC hit series revealed to EW there are more links to Wallace character left to the show which will delevop the series further.
"We will answer a very important question right when we pick up in the show and then we will move past it," he said.
"I think the question is what happens in the immediate aftermath of Wes telling this man, 'I think I'm your son,' and him getting shot while the man is on the phone? It's basically what will happen to Wes in those instant moments and there might be some reveal with that," he added.
The sophomore season also saw the disappearance of Frank (Charlie Weber), which is a major question fans are waiting to be answered.
Pete commented on Frank's disappearance saying, "Yes, I can see the three-piece suits and the hair product all falling apart. It's more what Frank feels about himself," which gave no strong hints to the fan about his whereabouts, but suggests he is somewhere to relax and unwind.
The third season will premiere on September 22, 2016 which will see the leading lady Annalise Keating (Viola Davis) possibly get a new love interest. According to her, mysteries will be unveiled from the first episode of the new season just like the previous two.
Luna-Velez is set to join the cast, and will be seen as the president of the Middleton University. It has been rumored she will play the new "love interest" of law professor and criminal defense attorney Annalise.
