"Sounds good to me. How long do you want to wait before storming in after me anyways?"

"Ten minutes?"

"Maybe give it fifteen."

"Sure, unless I hear screaming."

"Works for me!"

"Then I'll wait for your signal."

"I'll call you," she says with a wink, then heads towards the station. 

Ellie will keep watch outside in case any raiders or ghoul packs show up from elsewhere.

- Yeeeep that'd be a yes on the ghoul pack.

Grenade launcher time!

Grenade launchers: pretty damm effective against ghouls, actually, and this pack isn't as huge as the waves that had been attacking the Brotherhood of Steel. She's able to deal with them before any can get close to her and Jade.

Not as bad as those damn mutant cockroaches, but she still hates those things.

Hopefully all that noise didn't mess up Cat's reconnaissance.

There's no screaming from inside, at least.

She'll give it a couple more minutes.

No screaming starts! But the fifteen minutes elapses with no word from Cat.

Then Ellie's going in after her.

"Come on, Jade."

"I'll cover your back, Mistress."

And she'll brush the door aside and go stomping around looking for Cat.

She doesn't encounter any living enemies, actually - though there's some dead ghouls and super-mutants - but eventually finds Cat standing in front of a locked and scorched door with her arms crossed, glaring at a computer terminal.

"Uh. Hey. Do you... want help with that?"

...Huff. "Yeah."

"Here, let me." She can jack her armor into the terminal and get the onboard systems to help with some of the firewalls.

This computer system is stupidly complicated and actually seems to have been pretty significantly worked on over the last two centuries. 

Huh. An interesting challenge.

"...The good news, I think, is whatever's behind this door is seriously important."

Snort. "Good to know I didn't waste those minutes on nothing."
