I suggest a woman take this one, but men fill free.
Basically Hera and Sabine are synced with each other and share a refresher. (Girls you know what I mean)
Sabine is having her time of month and notices that for some reason Hera isn't. She walks into Zeb and Ezra's cabin where she finds Ezra alone. She then proceeds to tell Ezra about her suspicions about Hera being pregnant. She also ask him if he will check the force to confirm it for her since he has a talent for connections.
Ezra doesn't want to get involved at all, and ends up the unwilling victim of an incredibly awkward and personal conversation. Sabine teases him about how much he is embarrassed and nervous about this topic and tells him it's a part of life.
Ezra manages to escape from his cabin and gets to the safety of Kanan's cabin where Kanan is meditating.
Kanan looks up and starts asking Ezra what he did thinking he's in trouble. Ezra explains what is going on, and begs Kanan to do Jedi training or for some reason why being a Jedi padawan could get him out of this conversation. Much to Kanan's amusement I might add.
Kanan instead uses it a way to teach Ezra about attachments and that type of stuff. He brings up that it was forbidden by the order, but that he no longer follows that rule.
Then he leaves Ezra to think about it and goes to fill Hera in on the recent gossip. She decides she needs to talk with Sabine. Then Kanan returns to his cabin and explains to Ezra that no Hera isn't pregnant but if she was because of his talent for connections he would probably be the first to know. Ezra is a little disturbed by the idea that he would know possibly before Hera even did even if he can't help it.

Seven years later Ezra is 22 and lives at a place of his own above Kanan and Hera's new house. Hera is only there half the time. Hera leaves and Ezra pours Kanan a drink. Kanan is a little upset about Hera being gone when Ezra smiles.
"She'll be back in about two weeks with some news." Ezra informs him.
"How do you know?" Kanan ask.
"Her force signature has changed. Theirs another attached to it." Ezra answers.
Kanan realizes what Ezra means and tells him not to tell anyone else or let Hera know he knows until she mentions it.
Two weeks later she comes back and tells Kanan. Ezra is gone on a trip to get something at the time. He acts surprised and Hera suggest they wait a week before they tell the others.
Actually this part is where Closer in Living with Jedi takes place.
Hanni2034 actually inspired that one. This was inspired by another fanfic though. I just wanted to connect them.
