Syfy have released a trailer for the next episode Hero. I've added it to the Hero page with the episode descriptions.
The episode description from ITV4 for 2x04 - Hero :

An unlikely superhero with unprecedented strength and the ability to fly is intent on thwarting crime in the city, but his good deeds are interfering with the work of the Sanctuary. Magnus and Will manage to capture him, but when tests reveal that he does not possess the DNA of an Abnormal, they are baffled as to the origins of his powers. Kate risks the new-found trust she is developing with the team when she agrees to help her brother who is in trouble with a crime boss.

A few details have come to light about an episode called Fragments about Henry. I think this episode is number 6 and I have temporarily put the details on that page until I can get confirmation of the episode number. Follow the link to 2x06 - Fragments
