Let me remind you that Sherlock owns 23 and 24 Leinster Gardens. He owns these two big properties, but, when a cute soldier comes in, HE'S TOO POOR TO AFFORD A FREAKING FLAT ALONE
surface nonsense, absolutely.
metaphorically, hmm... a house might represent the self, or one's life situation. an empty facade, a bolthole, a bleak, narrow hallway: seems pretty lonely and dire. on the other hand it's a ventilation shaft for the trains, trains in tunnels. so there's air (thought) and trains (classic filmspeak for libido) so not totally depressed.
anyone else still into metaphorical readings? apologies to OP if this isn't where you wanted it to go, but nearly every time there's a bit of utter nonsense on the surface, it turns out to have a metaphorical reading that makes a bit more sense.
I don’t think it was ever about money in the show. (Look at how he dresses, the fees he refuse and how mrs Hudson easily would let them stay for free.)
I think Sherlock might have looked for a flat mate because he can’t really live by himself. (Though he does point out in ASIP that “together we might be able to afford it”, so I dunno.)
@sarahthecoat This is exactly where I wanted it to go. Thank you. Thank you to all the people in this fandom reading between the lines. THIS, the metaphorical, symbolic reading, THIS is why I'm here. Thank you.
(Also the trains for libido??? Is that true? There is some deducing to do about S3 because there are trains everywhere)
glad we found each other! the metaphorical reading is the one i keep coming back to also, though i enjoy reading all the theories and interpretations. fandom is broad and we bring so many different views to the story.
trains, especially trains going into tunnels, have been a cinematic metaphor for sex for a long, long time. not the only possible metaphor, but very commonly used. and in a show that seems to be all about sherlock's brain vs his body, it's not a reach. yes, there are trains everywhere in the show. i think it's interesting that trains figure prominently in TGG also, but only above ground. in TEH they go underground, and in HLV at last we have that ventilation shaft, linking the two states.
oh, and @alltingfinns brings up the money aspect. money is also a rich metaphor. it can be a substitute for emotions (even irl!) for example. so in ASIP, "together we can afford it" could mean "we'll both be much happier together" (so true!). mrs hudson's family discount represents her affection and gratitude. sherlock may scoff at money (sentiment) but he does always seem to have plenty!
