Back when Lilian still lived in Washington in his small home town him and his best friend Felix would hang out all the time
This picture is Lilian rambling on about space stuff Lilian really loves space and science he can talk about it all day and that's exactly what's happening here.
Felix enjoys listening to Lilian ramble about his favorite things even tho Felix doesn't know much about to the space science stuff it's still nice to hear for him
