Twisted yarn untwisted

I’m using a super bulky yarn that has two twisted strands to make a scarf using just a knit stitch. I’m near the end of the second skein and for some reason the yarn is no longer twisted, but just like two parallel threads. What should I do about this? Do I have to go through and retwist it all or should I just work w/ the two parallel strands? I don’t know if it would look different if I just did that. Thanks!!

Is it just a stretch of the yarn? If that’s the case, I’d cut it out and rejoin it.

I think you can just knit them as they are and it won’t make any difference to the finished item.
