Spoilers for 'The 100' Season 7 Episode 16 'The Last War'

The much-awaited series finale is finally here, and leave it to fans to have Lexa trend globally as Alycia Debnam-Carey makes an appearance when Clarke Griffin (Eliza Taylor) has to take the final test. If you're watching, you know that Bill Cadogan (John Pyper-Ferguson) is finally dead. Clarke killed him because Cadogan aka The Shephard left her daughter Madi Griffin (Lola Flanney) in a nonresponsive state to get the code that would take them to a test. This test would decide if the human race is worthy of transcendence or will it be extinct.

"ALYCIA DEBNAM-CAREY PLAYING LEXA AGAIN GOT ME CHILLS AND YEARS OF LIFE, THANK YOU @DebnamCarey #GratefulForThe100 #The100," tweeted one fan. Another added, "'m legit crying seeing lexa again and I haven't been in the fandom for years #The100."

After Cadogan starts the test, he is asked by his daughter Callie Cadgoan why he created a world without love. Just then, Clarke comes in to kill Cadogan. Now, she was set to take the test, only she ends up in an argument with Lexa who tells her that she failed the test and that the human race is not worthy. So, while we finally got a #Clexa moment in the series finale, it was a devastating one.

"WE SAW LEXA YES ALL THE CLOWINING WAS F*****G WORTH IT #The100," wrote one fan. Another fan paid tribute to the character, and the actor tweeting, "Omg @DebnamCarey made my 2020 so much better. To #the100 Thank you for creating such an epic character and for bringing #Lexa back one last time. #The100seriesfinale."

It seems fans knew that Lexa would be in the series finale, considering creator Jason Rothenberg has disappointed fans too many times in the series final season. "How did I know Lexa was gonna show up in the final ep. This dude had to bring in the fan favourite after the monstrosity of 2016. #The100 #The100Finale," wrote one fan. Another added, "Saving 2020 with Lexa coming back. #The100."
