Context: Loki did n\'t like the idea of me going to therapy , and he \'d always ask did you find out who the killer was , and when I \'d shake my head he always seem to have a calm almost relieved face . It makes me wonder . Sighing I leaned back in my chair " it was pretty well today , and beacuse I know you \'ll ask no I do n\'t know who the killer is .
