Seamus: Ahh. Woogie William. Woogie William. Oh, yes. (to Marty) I think you'll find the barn comfortable. I've never had any complaints about it from the pigs.
Seamus laughs at his own joke, like Marty's brother Dave does in 1985.
Maggie: Seamus. A word with you.
Seamus: Aye. (to Marty) Will you hold him for a minute?
Seamus gives William to Marty and follows Maggie into the corner of the room to talk.
Maggie: You sure you're not after bringing a curse on this house, taking him in like that? Such a strange young man.
Seamus: Aye, but I've just got a feeling about him Maggie. It's the right thing to do. It's important. Look how the baby takes to him. Little Will never takes to strangers. It's almost as if.....he's connected to us.
Cut to Marty talking to William.
Marty: Hey, Will. So you're my great-grandfather...the first McFly born in America.
Marty lifts William up and sees urine dripping down his (Marty's) legs.
Marty: And you peed on me.
SEPTEMBER 3, 1885
Hill Valley train station. Marty walks onto the platform, through the building and down the street. He passes "Honest Joe Statler - Fine Horses" which is on the future site of Statler Toyota in 1985. He also passes a butcher and a bathhouse where 2 MEN are talking.
Man 1: Give me some soap, Frank.
Frank: Here you go.
Marty continues down the street. He walks underneath a banner - "Hill Valley Festival September 5th, 1885" - and as an "A Jones" manure wagon drives past, Marty catches sight of the Hill Valley Courthouse - under construction!
Horse Driver: Hiyah!
Marty narrowly escapes being hit by a horse and carriage - stepping in horse "whoopsies" as he does so. Marty stares at his boots, before spotting the Palace Saloon on the future site of Lou's Cafe (1955), Lou's Aerobic Studio (1985) and the Cafe 80's (2015). Marty goes inside. The bartender, CHESTER, is at the counter wiping a glass. Three OLD TIMERS are sitting at a table (they are played by 3 Western film veterans!). They all see Marty and notice his outfit.
