Maybe it' s one of those hoses that fits on the kitchen faucet, like are used for dishwashers that aren't built in. A friend of mine lives in an older house that doesn't have the plumbing for a dishwasher, and that's what he has. It's just an ordinary piece of garden hose with a special end to go on the faucet end. I'm sure you could get longer pieces.
Yeah, the drinking game struck me as odd considering Faye's relationship with the booze -- she may not be technically an alcoholic, but she's showing tendencies to self medicate with alcohol. Of course, it could also be a "let's have fun like old times" thing, because getting drunk has been a major feature of good times in the past.
Could this be a means of driving Faye into Sven's arms beyond the occasional bootie call? I mean, relationships are about more than sex - they are about talking together and getting silly together and laughing together. Sven's thrown Faye an offer or two that didn't automatically include bumping crotches (the concert, for one).
I don't say Sven is Faye's perfect love, but he'd be a decent practice boyfriend, all things considered -- he's not likely to get hurt(or at least if Faye does break his heart, he's likely to bounce back), he's smart and independent, and he's not likely to cheat on her because he fears death from both Faye and Dora. Faye needs to at least practice having a relationship if she's ever going to get over her past and move on.
