Arrows Not Thorns

The only part of the rose I was never too fond of were the thorns. Now, I've been feeling the pricks and cuts for a while now and I've grown numb to the feeling... but they hurt more and more now.

I haven't looked at my wounds in sometime, I've just ignored it... but something's not right. It's time I tend to my wounds. The thorns I grew numb to have turned into arrows. They hurt so much more and are slowing my pace.

When did the thorns become arrows?
