Why doesn’t Matt bring Ando into Hiro’s mind like he did with Dafny. I know that he says something like "I don't know how I did it" but I would think that it would be worth a try...

1: Daphne not Dafny

2: Because you always just randomly try stuff that you have no clue how to do? Especially when you've had not time to practice? And when it's potentially highly dangerous?

He brought Daphne into a nightmare with him. That's different than holding on to another person's shoulder and letting them read someone else's mind. I don't even know if that can be done. Maybe this would work if he put Hiro into a dream and then brought Ando in. But I tend to agree with Synch, that'd be tricky and dangerous, and might backfire if it scares poor 10 year-old Hiro.

I agree. Matt doesn't know how to create a nightmare, so far he's only done breaking and entering. In fact we haven't even seen him convince someone to sleep. He got real good at illusions real fast, though. I think with more practice Matt could do anything Maury or Arthur has done but he's too much of a good guy to experiment on people unless the occasion calls for it.

I thought he locked Maury in a nightmare?

Yeah, but he didn't create that nightmare. Maury created it, Matt just ditched him in it and locked the door.

The fact is, I'm guessing, he will figure out a way to bring Ando in with him. Through Ando he will be able to fix Hiro. That's what I figure at this point.
