Having stopped in his tracks, hearing footsteps as it seemed to belong to Killian as he was now infront of him, telling about some chest that Eomer, he noted, seemed to probably think that this chest was nothing but a rubbish rumor or something of the sort. But with all that the Jotun had seen in his lifetime up till now, something like this was most likely possible. A chest that no one know what it looks like or the size of this chest. Containing the heart of Hades and whomever has it in their possession can make Hades do whatever he or she wants. The cons to this that he could think of already was that, they had no way of finding, could not possibly exist in the first place, and lastly be as dangerous as all hell coming from the man he trusted the least. Pros, he could possibly save the one man he loves. But what would happen after that? What would they do with the chest IF they found it? 

Not believing what he was going to do next, Loki enhaled and exhaled one big breath before crossing his arms over his chest. "And how would one possibly find it if this rumor is indeed true?" The Jotun asked, seeming to consider this option. For now.
