The power of believe was actually a pretty big deal as far as It was concerned. As children it had given them the power to defeat it, to hurt it. Even if that had only been temporary. They had disrupted It's feeding cycle and sent it back down into the depths of the sewers or wherever it had wound up. He nodded, agreeing with her. It meant a lot that she hadn't made fun of him for it or rolled her eyes. It wouldn't have stopped him from believing but he definitely would've had a reason to try and close himself off from her.
Even if he knew that they had come from similiar (yet completely different) circumstances he still would've chosen to focus on the normal aspects of life. Maybe it was impressive that his friends had gone on to kill something that seemed to be immortal and maybe he was unhappy with his own death but, really, who wanted to talk about that? The safer topics were better (even if they were only mildly safe) and if his potential new friend didn't mind hearing about mundane things like Richie's love for "your mom" jokes then what was it really hurting?
"Maybe clear your schedule. It might take a whole afternoon." He teased, certain that neither of them had a schedule to keep anymore or anywhere to be. Maybe he'd see about talking Richie into picking out furniture so Natasha would have somewhere to sit while they talked.
The house, itself, wasn't creepy. Walking up to it was like walking up to any of the other ones Eddie had decided to go out and inspect the structural integrity of... or whatever excuse he'd given himself. The difference, of course, was the interior and the doors. To his surprise none of them looked all that bad. There certainly weren't any options written in blood upon them. Whether or not that was a relief depended entirely on what was beyond them. Like Natasha said, others went through for supples. It couldn't be that bad. Maybe they could find one that opened to a pharmacy and he could find an inhaler (so Richie wouldn't yell at him to just fucking breathe during an attack again) or something more useful. "Yeah..." He decided. "Let's try one." If it opened up to a closet or a demon pomeranian again he was going to be pissed.
