The best way to pick up this dropped stitch in my sock???

[justplaincharlotte]

Last night, I was knitting along quite happily on this sock until... just until.

I tried to tink the first repeat because I started a pattern row(wrong) instead of the purl row(correct). When I did a stitch dropped, which one I'm not sure because of the yo. The pattern repeat is k1, k2tog, yo, k1, yo, ssk, k1. I did manage to catch the dropped stitch with a split ring holder so that I would merely fume a bit instead of cry.

Do you think there's a way to work a vertical fix here, or would running a lifeline and frogging back be the best bet?
