One thing to say;
"Well, that escalated quickly!".
But seriously... after that arc, wtf happen? Things are going too fast..
Firstly, Colonnello married to Lal? Wtf? I wondered how did that happen, I mean there were hints that they both liked each other, but I thought Lal was more of a tsundere character, also Conollelo is still an infant. In a common sense point of view, everyone will think "pedophile".
Secondly, Tsuna confessing, somehow, I cannot see that happening or at least, gonna go well...
