Well, Jared was, after all, pretty important in this love triangle (i dont think its really a triangle, some other shape would probably be better..perhaps a square...). He was (other then Jamie) the only thing Mel cared about! Jared, he was SO thought-less, i mean beating her, then risking his LIFE for her! I mean it sounds like all his actions were spur-of-the-moment-reflect and the-first-thing-i-could-think-of kind of actions! But on the other hand i suppose (in some odd way) i do understand him. He had fallen into the trap of hope when he had ment Melanie, he had imagined he would spend the rest of his life with her (no matter how his life would end) and when she had "died" the trap had snapped shut, holding him heart-broken forever, afraid to hope again. Then when Mels body shows up again, how could belive it was actually her? And fall into the trap yet again. In the words of Wanderer "To good to be true." (or something along those lines)
Anyways, regards to Mel&Jareds relationship i found that the bond there was incredubly strong, strong enough to suck someone ( i.e Wanda) into it.
Strong enough to last the end of the world.
