Adu Du and BoBoiBoy vs. Ejo Jo

(Warning: Flashing lights and Season 2 spoilers) Adu Du comes to BoBoiBoy's aid just before he's finished off, so he can help him destroy Ejo Jo for good as revenge for causing Probe's death. Adu Du is quick to remind that he's only working with his enemy this one time to defeat a mutual threat.
