**********SPOILER SPOILER********
At the end of the quest after i placed the explosive i have to walk up to Desdemona and she gives the order to transport us to the relay room

I get transported right out again to the surface. (Its a 2 step transport I think for a second im in the relay room)

without my companion and without the option to fast travel. But i still need to talk to Tonker Tom and Shaun jr.

I tried the mission several times with diff chat options for shaun and with and without power armor.

But the outcome is allways the same.

Anybody has a solution or workaround for it?

Press the button than you can fast travel after the cut seen.

By the way this should be in spoiler section

Oops i was to hasty to post didnt read the sticky's

Tnx for the responce. ...But.....what cut seen what button?

i just walk up to Des and i get 2 transport i a row.

So... After a few more attempts i consoled my way out.

I found the ref id of synth shaun (0005c338) And ones i was on the surface I used Player.moveto 0005c338 in the console and i was there.

Ccould talk to everyone and finish my quest the way i should.
