The joke is that whenever the team got themselves into a pinch, the frenzied Akari and the freaked-out Zenjirou would always call for Taiki to fix the problem.
Blastmon's not only the biggest narcissist character out in this season, but likely implies homoerotic pheromones or the likes of it.
I said this because Blastmon's rather than the Code Crown was more interested in the secret treasure of the ruins.
He got his head so full of himself that he literally crashed into the wall, and dug his way out into the desert where Nene and her team literally moped the floor with his army.
To his suprise Blastmon found himself ambushed by Kiriha, who summoned Cyberdramon to perform a kamikaze attack involving blowing itself along with Blastmon.
The joke or maybe one-liner of this week was that Blastmon misinterpreted Cyberdramon's kamikaze attack as a hug of love:
[Clutched within Cyberdramon's claw in a bear hug]
Blastmon: I'm being hugged...
[Cyberdramon starts to glow]
Blastmon: Does this mean....
[Glow engulfs Blastmon]
Blastmon: ...that you love me?!
[Giant explosion rips through the desert]
