After a long night out, Jace and Simon come home and make love.
After a few weeks Jace wakes up and is violently sick. Simon suggests that it's probably just the flu, but after another week, the symptoms get worse, he experiences mood swings, cravings and shockingly..weight gain. Simon panics when he realizes what the symptoms are related to and calls Catarina.
She runs some tests on Jace, and what she finds shocks them all.

Jace is pregnant.
