What's trending for Wednesday, Apr. 18th – Boy with cancer gets to be Batman, a possible lost album for Kurt Cobain & all five Star Trek captains to reunite

On Early Start this morning, Zoraida Sambolin and Kate Bolduan look at the stories trending on the web, including:

* The Arlington, Texas police department made a sick little boy's dream come true. They let him be Batman for a day. The department set up fake crimes across the city for 'lil Batman to solve, including a bank robbery with the Joker and a phony bomb scare with the Riddler. The mayor even gave 7-year-old Kye, who has leukemia, a key to the city for saving the day.

* A friend of the late Nirvana front man Kurt Cobain tells Fuse TV that Cobain was working on new solo tracks that transcended anything he'd written so far. He added "It would have been his "White Album," referring to the Beatles's double album that inspired music more than 40 years ago. The big question – do these demos still exist?

* A Star Trek convention in the U.K. is set to unite all five captains on the same stage for the first time, including William Shatner, Patrick Stewart, Avery Brooks, Kate Mulgrew and Scott Bakula. Organizers say they will all attend "Destination Star Trek: London" in October. And they're expecting thousands of Trekkies from around the world to attend.
