"The Vampire Diaries" is scheduled to come back with episode 18, "I Could Never Love Like That," airing this April 16 2015. A new promotional trailer for the episode has been launched online and it gives a few details regarding what fans could expect, particularly with the confrontation of Lily and her son Stefan Salvatore.

The trailer reveals Damon Salvatore and Elena discussing how Lily may help Stefan get his humanity back after Damon gives Lily a small pep talk, preparing her for what Stefan has become in the years they have not been with each other.

Episode 17 revealed Lily's background story as a witch banned inside a prison back in 1903 after she was found responsible for the death of thousands of people. Her change and decision to leave her past behind may give hope that Stefan could still redeem his humanity.

Stefan and Caroline, on the other hand, look like they have no plans of looking back and are in fact plotting to kill their own friends, Tyler and Matt. The video shows Caroline and Stefan choosing with a coin toss who of the two gets to kill and which person is set as their next target.

Previously, the two attempted to kill Alaric and Enzo and hunting either Tyler or Matt is not something new for this dangerous duo.

Elena and Jo are also shown dealing with problems of their own. As they work to treat the victims of Stefan and Caroline's killing spree, Elena discovers that Jo is pregnant, forcing her to re-think about her vampiric life.

The trailer ends with Lily confronting Stefan and Caroline. When Caroline asks who the woman is, Stefan replies with a shocked look on his face, "It's my mother."

Episode 18 could see the death of Tyler or Matt and this could be episode deciding whether or not Stefan will return to his humanity or fully embrace a murderous, violent life of a vampire.
