Ember's brief conversation with Clod is unironically an important foreshadowing for the themes of the movie and a microcosm for the whole movie.
"June Bloom is coming up." June is a thematically significant part of the year, marking a change of the season into summer, much like the change Ember and Wade are due to have over the next few days that would lead to a flourishing prime of their life. It also shows that worldbuilding/humor is mostly pun based, as it lampshades the fact that there's an Elemental Roman empire (colonialism and immigration themes), elemental Gregorian Calendar (keeping with tradition), elemental God(s) [authoritarian father figures]...
The flower he picks when he goes "Check it out, I'm all grown up" is purple and yellow like the flowers that become important later in the movie. Purple is the color of royalty, like Wade, and yellow the color of danger and respect like Ember. Once again, this flower ties to the themes of moving past the spring of your life and into the unfamiliar territory of Adulthood. Clod is both recognizing it in himself, and projecting it upon Ember, who is struggling with this issue on a personal level. Ember struggles with breaking her comfort zone hence why he insists she's got to be his date.
Ember takes the flower and it doesn't burn (like how she takes a hand safely later), until she deliberately burns it saying "elements don't mix." An axiom she'll learn is wrong later.
I could go on, and I have gone one, but there's a character limit.
