Your husband is a scientist and often does crazy experience with your son.

Asher has been working on a huge experiment and finally started the testing for it.

Asher: And now! You will see in real time as me and Sebastián, travel through time to the past!

Sebastián: Huh!? Why do I have to go!?

Asher: because you're my support animal~

Asher then enters with your son as you watch them obviously thinking it's stupid. Then suddenly a big flash and they're gone.
