Marsh and Vin

[Firespir]

So in chapter 20 of the first book Marsh arrives in Felise to teach Vin some Seeking. 

At some point Marsh mentions the first time she used allomancy to influence his feelings was 8 months ago in his workshop and Vin wonders why she doesn't remember their first meeting. 

So, why doesn't she? Is it even significant at all? Am i grasping for straws? 

It just seems like a random conversation but I can't help feeling there's more to it.

It could be to highlight the difference between the two brothers. No one who has ever met Kell would forget it. But Marsh can be unassuming.

I don't know if there is any significance to Vin not remembering, but the encounter is referenced earlier in the book.

"Kelsier munched contentedly on his cakes. 'How'd you find out about her?' he asked between bites.

'Your brother,' Dockson replied. 'Camon tried to swindle marsh a few months ago, and he brought the girl with him then too.'"
