I also asked about the connection between the spren and surgebinder, such that the spren turns into what the surgebinder wants, like In Edgedancer, Lift turns into a bar of metal and into a Shardfork. Wyndle himself isn’t “in tune” with Lift, so his turning into something that she needs with no prior warning …
Since the spren fill in the soul, they’re connected on that level, so like their minds are separated, but since the souls are melded/connected/same that the spren can turn into stuff the Surgebinder wants. This is heavily paraphrased.
