Buzz (look no amnesia!) and Jenna happy again. 

Jenna (infanticipating) and Harley, now best of friends at
Annie's Non Wedding (Jan 1998) 

Pregnant Jenna with a comatose Vanessa who just
gave birth to Maureen Reardon (Feb 1997)

Buzz and Jenna on the way to Lamaze: June 1998  (off screen of course :-()

Jenna goes into labor with Ian Stavros Cooper: June 12, 1998
(after an 11th month pregnancy)

Buzz thinks it's a great time to get married 

Even if Jenna's rather preoccupied. 

They finally wed June 15, 1998 right before the birth of
Ian Stavros Rocky" Cooper with family, friends and a horde of strangers
in attendance...(GL really went all out and spent the big bucks on this wedding.)

Harley visits Jenna & Buzz and the littlest Cooper.
