Oh dear! Now it's a question of 'Does alcohol affect puppets the same way it does with humans?'.
Regardless, this "unhealthy hobby" of Spencer's could make him spiral even faster! Heck, what if he starts operating his engine while under the influence? He's putting his life in danger! Whose going to teach Thomas all about mythical creatures if he kicks the can? (If I remember correctly, Spencer likes mythical creatures) He's going to need an intervention. Maybe Scott, Gordon...maybe even Mama and Papa Gresley, or the couple that raised him (I forget their names) could intervene. Or do they know? If they don't...well...
Scott, Gordon, your cousin Spencer is spiraling...
Puppets can get affected by alcohol a similar way humans can though not all puppets can get affected by it the same way it truly depends on how much their golden wool can handle-
heck even Scott can get affected by alcohol, if it's regular beer that won't affect him one bit.... but when it's something stronger he's a lil bit of a happy drunk..
Though Truro cannot get affected by alcohol as much- eventually after enough drinking that can kill a group of people he might get tipsy
....
But anyways back to Spencer...
He's taking a day off or two...
