If you're talking to her for the Stoneheart quest, at 8PM she'll stop talking and say "The day has ended and I shall spend my evening inside the safety of Bjarken." then walk to location ~11K, 58K in Bjarken, you can then continue to speak with her. She exits Bjarken at 6AM, saying "Day has come and I shall greet it beneath the trees.", to go back at previous spot, 9K, 49K.
New screenshot to take, she now has brown hair! ;)
