These are the ways to bother Artemis... Just make sure you have backup when you do...
Send her a video of Ash and Tory.
Have the Simi start a conversation with her
Pull Acheron out of her home
Dye her hair a different color
Send Tory to visit
Have Katra and Sin tell her she is a grandmother
Become rogue (worked for Zarek anyway)
Get your soul back (only works if your a dark-hunter)
Tell her Acheron is dead
Kiss her in her own temple
