Towards the end of the last episode of Serial Experiments Lain, we see Lain have a brief conversation with her father. At the end of it, her father says:
Lain, I'll make us some nice tea next time. Hey, with some madeleines! Definitely. They're great!
This seems to be a reference to Marcel Proust's "episode of the madeleine" in In Search of Lost Time. Assuming this is the case, is there any significance to this reference in relation to plot beyond the fact that (according to Wikipedia anyway - I haven't read Proust yet) in Proust, the madeleine is connected to a discussion of memory?
Given that this is followed (or follows, possibly) some comments on memory in the anime, it would make sense for this to be a "standalone" reference, but I'm wondering if there's any significance to this other than it just being a reference to a literary discussion of memory. (For instance, is there anything specific about Proust's discussion of memory that's also relevant in the context of SEL?)
