Did the quest on first solo try (60 hunter) AND tamed that gorgeous grey lion... helps that im a BA hunter.(BA as in BADASS!! )
         
          HERES WHAT TO DO:
         
Step 1: stable current pet in Everlook (Alliance BTW)
Step 2: go to frostsaber rock and tame ANY frostsaber
Step 3: kill frostsabers until SACRED MEAT drops
Step 4: go to rock and summon Shy
Step 5: Send pet after Shy (try to keep her in between rock and cave entrance to ensure Sian shows)
Step 6: get her down to about 35% health and she will call Sian
Step 7: FEAR SIAN and kill Shy
Step 8: abandon pet and lay freezing trap
Step 9: TAME SIAN



      GOOD LUCK AND HAPPY HUNTING!!
