That is actually brilliant. Let me one-up you – what if the “sofa” is Phan and it’s all just a metaphorical re-enactment of 2012 and how Dan and Phil are hiding their relationship from us?
In the scene where Stuart goes to Dan and Phil’s house (starting at 12:24), Dan opens the door very fearfully, then seems relieved to see Stuart. Phil says they thought it might be someone else – the people (they live in constant fear that we might invade their privacy – depicted here as their house). He frightfully explains that the people are “always watching” (wherever Dan and Phil are, the shippers are always watching their every move extremely carefully in the hopes of spotting even the tiniest sign of a relationship). Stuart says he came because he is looking for a sofa (Stuart represents the confused fans that went to Dan and Phil for answers after the Video started to spread in late 2012). Don’t forget that in this clip Dan and Phil are protecting the secret of the sofa’s location, which they know though they pretend they don’t, i.e. the truth of their relationship. They have the following conversation:
D: A sofa? (laughs nervously) What makes you think we’d know anything about a sofa? [The sofa symbolizes the concept of Phan.]
S: Somebody specifically told me it was here. [“Somebody told me you were in a relationship.”]
D: Well, somebody lied! [In 2012, Dan said all the social media updates that “prove” Phan were lies; here he is referring to himself as “somebody”. He erases ownership of his lies, because he is feeling guilty and anxious.] I don’t even know what a sofa is! [Of course Dan knows what a sofa is; this is symbolic of his anti-Phan phase in 2012 when tried to deny absolutely everything that had to do with Phan.] You can’t prove anything! [Literally what he said to us back in 2012.]
P: Calm down, Dan! [Phil, who tried to stay out of the turmoil of 2012 tries to calm down Dan, whose fear of their secret relationship being revealed is getting out of hand.]
After this, Dan’s attitude changes to pleasant again (as it did shortly after his most expressive rants) and they invite slightly suspicious looking Stuart inside. Stuart then asks why they always open the door together, i.e. why Dan and Phil always seem to do everything together, even though they so strongly deny being in a relationship. Oh God, it all makes too much sense!
I’m obviously joking. I’m a little ill at the moment (in case you couldn’t tell from this answer); that’s why I only have very few asks for you guys today, I’m really sorry! I’ll be better tomorrow, I’m sure. I just couldn’t pass the opportunity to write an answer to an ask like this while slightly feverish. Anyway, thank you very much for this rather unusual observation and I hope this answer was everything you hoped it would be. Have an amazing day/night x
