The S4 premiere of FALLING SKIES airs tonight in the USA on TNT. Aaron will be in episode 5 (4×05: Mind Wars) which airs July 20th. But I’ll give everyone a reminder as it gets closer to the date.
UPDATE: In Canada the S4 premiere is June 26th on Super Channel and Aaron’s episode will air on July 24th.
In Australia the S4 premiere is on June 26th on FOX8, so Aaron’s episode will air July 24th (same date as Canada).
In the UK the S4 premiere is July 15 on FOX, so doing the math that means Aaron’s episode should air August 12.
