What is the reference in the scene where the husband jokes about naming children? In episode 10, when the couple is discussing children's names, the husband makes a reference by saying "If it's a boy, then Shinji. A girl, then Rei" （男なら「シンジ」、女なら「レイ」）.



What is the reference being made in this scene?
This pose is typical for Gendo Ikari from the Evangelion series. It even has a page on knowyourmeme and is also featured as an example for 'Finger Tenting' on tvtropes.



In the series he has a son named Shinji and daughter (sort of) named Rei.
(The reference right afterwards is also to Evangelion's Kaworu)
