‘The Vampire Diaries’ Season 8 Episode 15 Spoilers: Katherine Returns As Matt’s Mom

"The Vampire Diaries" Season 8 Episode 15 sees the return of Katherine Price. However, she may not appear in the flesh but presents herself using Kelly Donovan's body. Photos for "We're Planning A June Wedding" shows Matt and Damon confront Kelly, who eerily adapts a resemblance to Katherine.

The events in Episode 14 cemented Katherine's return in "The Vampire Diaries" Season 8 Episode 15. Kai told Bonnie that Cade's death left his spot as Ruler of Hell open. Naturally, Katherine is next in line. This means Katherine becomes so powerful that she can easily come back from the dead and return to the living.

This seemingly happens in "The Vampire Diaries" Season 8 Episode 15, "We're Planning A June Wedding." After Kai's revelation, Bonnie, Damon, Caroline and Stefan plan a way to lure Katherine and end her once and for all. What better way to bring her out of Hell than a Steroline wedding. After all, Katherine has been in love with Stefan for centuries, according to Digital Spy.

This is exactly what happens in "The Vampire Diaries" Season 8 Episode 15. The trailer shows Caroline and Stefan marry under Damon's suggestion. Caroline even wears Katherine's necklace as she walks down the aisle, which seemingly only angers Katherine more.

However, Katherine is smart enough to realize that she is being tricked to come back. Instead of appearing in the flesh, she compels someone to sabotage Caroline and Stefan's wedding. Promotional photos for "The Vampire Diaries" Season 8 Episode 15 from TV Line, teased that she controls Matt's mom, Kelly, instead. Kelly wears her hair like Katherine and even dresses up like her.

Similarly, the trailer for "The Vampire Diaries" Season 8 Episode 15 teased Kelly and not Katherine is in Mystic Falls. The penultimate episode may not see Nina Dobrev reprise Katherine at all, but she returns as Elena Gilbert in the finale.
