The two nerds were excited to see if anything they gather would help with the investigation. Barry stayed outside of the house. He was standing outside Alice's window and Spencer lifted it. It made a rather loud noise as it was forced to be open. They eyed each other before Barry tried to close the window from the outside. It wouldn't budge even with Spencer's help [He had crawled out the window and Barry couldn't help thinking how cute that was]. They locked eyes with a look that seemed to say "Well that possibility is out."
Instead of going through the door like normal people both Spencer and Barry crawled in through the window. Barry closed it and it made a loud squeaking noise. They tried with every window in the house and the only one that didn't make a sound when it opened and was easy to close from the outside was the window in the parents' room. It was an interesting piece of information, but neither knew what to make of that.
Spencer was trying to figure out how everything fit together, but really the only way for the kidnapper to get in and out was if she/he used a key. The blood by the window must have been just something to throw the cops. It has to be. 3 cases, 3 flowers, and 3 drops of blood. It had to be a set up. Barry had offered to drive them back to the station when Spencer was struck with an idea.
"What if the kidnapper had a key?" Barry nodded intrigued by the idea. They had already concluded that as one of the possibilities. "Think about it… this person has done the same thing 3 times that we know of. There is no way the windows could be used without being caught. This man or woman must have been watching their every move."
"Did they have a house key hidden outside somewhere? Or maybe our perp somehow got a copy." Spencer nods and his hair falls over his shoulder and hides a bit of his face. Barry pulls into his parking spot at the station [which usually went un-used since he didn't have a car. It only made since to share the one special privilege he had with Spencer. What were partners for?]
"If you're right then there will be evidence of someone following this family." He looked at Spencer and he had brushed his hair back behind his ear. Barry liked Spencer's long hair, it made him look more of a geek. Barry kept his hair short, but he was told no matter what his hairstyle was he'd always look like a nerd [thanks Joe].
Suddenly Spencer looked excited. He whipped out his phone and after some quick dialing he placed it against his ear. Barry waited, his curiosity growing. Spencer spoke quickly to a woman by the name Garcia. After five minutes Spencer hung up. "We have a lead."
