On this week's episode of FlashForward, viewers bid farewell to Al and said hello Blue Hand associate Jeff Slingerland (Callum Keith Rennie).

The latter won't be the final new character introduced on the series, not by a long shot, says creator David S. Goyer. He told MTV:

"We're introducing quite a few new characters down the line. We have already written [the Somalian boy from episode three] as an adult. We're hoping to have a certain actor play him. We haven't nailed it down yet, but we're crossing our fingers."

Goyer also hinted that Michael K. Williams (Omar from The Wire) would take on that adult role, which would be incredible.

Then there's Miles Fogel a new addition to be played by Michael Ealy.

"He effectively becomes a series regular with [episode ten]," Goyer said of Fogel.

Goyer also confirmed that Slingerland would turn up a couple more times this season; and that episode nine will take Bryce to Japan (as hinted at last night).

"That's the subject of episode nine, which is almost entirely his episode," said Goyer. "We introduce another of our cast members in that one — her name is Keiko. She's from Japan, and I can't say too much more about who she is, but she's involved in Bryce's story."
