The relationship between Chuck and Morgan would be explored further in the fourth season now that Morgan is in the know of the spy world.
One month away from the season 4 premiere, a featurette of "Chuck" is released to tease on what will happen to Chuck and Morgan. Some scenes taken from the last season when Morgan finally found out that Chuck is a spy are inserted before creator Josh Schwartz explains the quality of bromance between them.
Schwartz revealed the reason why Morgan was let into the world of spies, saying that the relationship was so crucial in the first season that the only thing that would get them in the same screen would be to reveal the secret to Morgan. Joshua Gomez who plays Morgan chipped in, "I'm like a [Spider-Man's girlfriend] Mary Jane now, which is odd."
"Chuck" returns to NBC on September 20 with the episode "Chuck vs. the Anniversary". TV Guide has just disclosed that actress Tia Texada will guest star as Hortencia aka Armand Assante's character's wife. Coming with a secret, she will be introduced when "Chuck and the gang visit the Premier's beautiful island in his native Costa Gravas."
