Well that's incredibly alarming and a thing to keep note of. Tommy being allowed into the Nether is good, any freedoms he's allowed is good, but-- it has not been that long and Dream is having to drag him back from tall edges. (Which is maybe less of a concerning thing in this world, death being what it is. But still.)

Also who's letting Ghostbur into the Nether. He is going to die immediately. ...again.

Ghostbur does not in fact die immediately! The group is headed away from the main nether hub, in a different direction than Ranboo and Jingyan are approaching it. 

“That seems, uh, kind of… not great. Definitely not the best,” Ranboo says. 

"We will have to keep an eye on it. ... At least Tommy is getting to see a friendly face."

"Ghostbur, you mean? Yeah. It's, uh. Yeah. I'll... see if I can visit Tommy soon? I'll, uh, leave him mail, at least."

"Once the walls are down, I'll try and find him. There's something I need to check with him."

"...What is it?"

"--Whether he wants to see Tubbo."

“Oh. Yeah, that—that makes sense.

I, um. I hope it goes well. They… They do care about each other.”

"It seems that way, yes. And I understand why Tubbo wouldn't want to... assume."

“Yeah. 

I hope they’re both— okay. As much as they can be, under the circumstances.”

"I hope the circumstances can be over as soon as possible."

“Yeah. I think— I think we all want that. Well, except Dream, I guess.”

"All the more reason to stop him."

“Yeah.”

The other group out of eyeshot, Ranboo will head back through the hub portal. 

There's no reason to stay. He follows Ranboo.

Ranboo will head back to L’Manberg. The walls: shorter! At this rate they’ll be gone by tomorrow. 

"We won't be being watched as much soon," he says quietly to Ranboo.

“That’s good! That’s— that’s really good.”

"It will be a weight off my mind, for sure."

“Did you, um, have anything you were going to be doing? I was just going to—see what Fundy’s up to, maybe do some more mining if he’s busy, but I don’t really have any plans.”

"I do not have any plans that aren't waiting for the walls to come down, but I would not want to get in your way."

"Oh! Oh, no, it's, um. It's fine, you're not in my way. If you want the walls to come down faster you could probably mine them also...? But you're not in my way at all, you're totally fine."

"I'll leave you to go talk to Fundy or go mining; I have something I need to speak to Tubbo about."

"Alright, goodbye!" Ranboo waves and heads off.

And Jingyan goes to find Tubbo if he is available.
