Fallout 4 Hoe Beau with a Shotgun pt 45 of 46

Fallout 4 Vanilla No Mod, traveling with a Hobo ghod,
G.O.T.Y. on PS5, no console commands, just shuck and jive.
Traveled to Institutes heart. Looking for son, found old fart.
Cutting through Advanced Science, brief respite, thunderous silence.
And now here at journeys end, a sad tale that will offend.
I am not a hobo ghod, 'parently I need a mod.
Broke the sequence way too far, guess I ain't no speed run star
Need to get to the railroad, to make institute explode.
Fast travel was disabled, travel mod on the table.
Also one mod to fix quest, yeah that's also for the best.
