Curate, connect, and discover
Danny accidentally finds himself in the middle of a fight between Lobo and Superman and is not pleased at all. He had assignments due and these two idiots decided that a royal rumble was just the thing he needed at 4 a.m.
So he may have said a few unsavory words towards them which resulted in them halting completely and listening to him in shock.
Now they both think a child from their species survived and has been hiding here on earth because Danny was unaware he gained omnilingualism.
