After eight successful seasons, The Vampire Diaries has come to an end. The series finale went down on Friday night, and the cast took to Instagram to say their final goodbyes. Nina Dobrev shared a series of snaps with her costars, including Zach Roerig, Kayla Ewell, and Candice King, and penned several emotional messages. Ian Somerhalder thanked the show's fans, while Paul Wesley took it back to 2010 and posted a throwback shot of him and Nina. We hope you've got some tissues nearby.
