'The Walking Dead' Here's how Twitter reacted to the death of your favourite character on show

On Sunday's episode of 'The Waling Dead' titled 'Thank You,' a favourite  and original character of show was killed off.

The episode killed off Glenn, who  was dragged into a sea of walkers by Nicholas' dead body, and eventually torn to shreds.

Why does Glenn's emotional death remind us of 'Jon Snow's supposed death?

The Twittersphere has been thrown into mourning, and of course different theories have surfaced online, explaining why Glenn can't be dead.
