Denton recently returned in the minecraft role play about Dr_Horrible's sing along blog and is working with him.
The video is about Dr_Horrible being beat up by Captain Hammer (A skeleton with a steve head) And Denton saves him with the Anti-Festivities Command Block under the condition that they work together. Many people speculate that this happened before DanTDM destroyed the Anti-Festivities Command Block, or when he did the block turned blue. Dr_Horrible couldn't bring himself to kill Dr_Trayaurus, so Denton used the Anti-Festivities Command Block to put him under snow. The clone of Grim saved them. See Grim's clone.
