The Queen Bee started talking like a human...
No, it's not talking, it's communicating using its mind to us which is why we can understand what it was saying.
"Telepathy?!" Tina is baffled.
Gobu and Lina are shocked as well but it seems their attention is not on the Queen Bee but on Cotton who is just standing there, staring at the Queen Bee paying respects. Cotton is releasing an aura that someone like her should have not possessed just yet. Also, her eyes are glowing green color.
Speaking of respect, didn't the Queen Bee just say that she is greeting the Insect Queen? What was that about and why is she doing so in front of Cotton? Does that mean the Queen Bee is identifying Cotton as the Insect Queen she is speaking? It's not Tina she is talking about as she is directing her eyes on Cotton and the former is far from her to do a paying respects gesture like that.
