The next morning, Bonnie woke up in a bed with a pounding headache. It took her a moment to remember she'd gone home with Derek the last night. Her dad was probably freaking out. Serves him right. She couldn't help the thought. She got out of bed and pulled on a t-shirt from the floor. It clearly wasn't hers, as it reached her knees, but it would do. She didn't know if Derek had any roommates. She left the room and continued down a flight of stairs, figuring it would lead to either Derek or the kitchen.
She found that it led to both. "Coffee?" Derek offered.
"Thanks." She walked across the floor, and surprised him by pecking him on the lips as she grabbed the mug from his hands. They walked over to the table and sat quietly, both unsure what to say.
"This is cozy." A man said as he descended the stairs. Bonnie tugged the shirt to cover her thighs in her criss crossed position.
"Peter." Derek acknowledged, not looking at the man, but picking up a paper from the table.
"And who is this?"
"Bonnie." Bonnie greeted.
"And I'm-"
"Uncle Peter." Bonnie interrupted. "I know."
"You do?" He smirked as he sat at a seat, glancing at Derek who refused to meet his eyes. "Well, my dear nephew failed to tell me anything about you, dear."
Bonnie shrugged, before gasping. "There it is!" She bounded to the island where her phone sat. She turned it on and saw many, many calls and texts from her dad and brother, a few from Scott, and then the normal messages from the Mystic Falls gang.
"You bagged yourself a popular one." Peter laughed.
Bonnie shrugged. "I've got to take this." She sighed. She never got to call Caroline the night before, despite what she said to Stiles.
"Hey, Care."
"Bonnie!" Caroline gasped. "I didn't hear from you! Are you alright?"
Bonnie leaned against the island, facing away from Peter and Derek, the former continued looking at her, and both men were listening in to Bonnie's conversation, interested in her life. "I'm fine, Caroline. I met up with a friend last night." She said quietly.
"Oh, Bonnie Bennett, getting all promiscuous only a few weeks after she leaves Mystic Falls!"
"I really can't talk about this, Caroline."
"You're still with him! Bonni-"
"Say another word, Caroline, and I'll start regaling your relationship with Damon. Oh and remember the time you and Klaus-"
"Enough!" Caroline squealed. "We'll talk later, okay?" She hung up.
"That was my friend, Caroline." She turned to Derek and Peter, who were both looking at her now. She shrugged. "Does anyone know where my pants are?" Derek choked on his coffee and Peter laughed outright.
Bonnie had been unable to find her pants, not that she had looked that hard. She was reading on Derek's couch as he was checking his e-mail.
Bonnie jumped and ducked when the door slid open with a bang, being used to ducking from Mystic Falls' many violent altercations.
"Derek!" A familiar voice called.
"No." Bonnie groaned and didn't get up.
"Scott. Stiles. How nice to see you." Derek panned out.
"Look who's here." Peter walked down the stairs, only enough to see the intruders.
"We have a problem." Stiles started. "My sister, she didn't come home last night."
"Sister?" Derek asked, confused as Bonnie got back on the couch.
"Hey Stiles. Scott." Bonnie cringed, knowing what was about to happen.
"Hey Bonnie." The boys said before double taking.
"Where the hell have you been." Stiles stalked over.
Derek's eyes widened. "You have got to be kidding me." And Peter looked as if Christmas had come in September.
"And whose shirt is that?" Stiles continued, now standing in front of his sister.
Bonnie decided against answering."How do you know Derek?"
"Derek?!" Stiles looked like he was about to have a coronary. He looked between the two, and then at Bonnie's exposed legs. "You did NOT sleep with Derek Hale, Bonnie."
"I slept with Stiles' sister."
"How do you know each other, seriously?"
Stiles turned around, his face purple. "Dude, you slept with my sister!" He yelled. He whipped back around to Bonnie. "Oh you know, dad arrested him for murder, Bonnie!" He yelled.
Bonnie raised her eyebrows. "Did you kill someone?" She asked, relatively used to being around murderers. but hoping her new maybe-boyfriend wasn't a murderer. Or at least not a serial killer.
"No!" He yelled, outraged, though a small voice in the back of his head reminded him that he had killed before…Paige…Peter. "Seriously?" He asked Stiles. "How are you two related? I mean Bonnie Bennet? Stiliniski? And she's black!"
"Seriously? That's what you pick up on?" Peter laughed.
"Shut up!" Derek, Stiles, and Bonnie yelled.
"I'm his half-sister." Bonnie shrugged. "Are you friends or something?" She shrugged, not totally uncomfortable.
"Or something." Derek mumbled.
"We're leaving." Stiles said, grabbing Bonnie's arm before she wrenched it out of his grasp. "Let's go, Bonnie!"
"You're not my father, Stiles."
"That's right. I'm not. Because our dad is at the Sheriff's station waiting for the twenty four hour mark to declare you a missing person!"
Bonnie rolled her eyes. "Well, you saw me. I'm fine. You can tell him." She crossed her arms.
"Like I'm leaving you here!"
"What are you going to do, Stiles? Drag me?"
"If I have to!"
Derek intervened before it could get any uglier. "I think it's best if you leave, Stiles." He stood between Scott and Stiles and Bonnie.
Stiles was about to protest before Scott whispered something in his ears. Before Stiles flung his arms in the air and yelled nothing and storming out.
"My brothers, gentlemen." Bonnie sighed. "I'm sorry. I'll leave, now. I just didn't want to go with him."
"You don't have to leave, Bonnie." He tilted her head up. "You should probably call your dad before Stiles convinces him I kidnapped you, but you can stay if you want."
Bonnie smiled and leaned up to kiss Derek.
Over the next two weeks, the Stilinski household was unbearably hostile. The only words exchanged were those of between the two younger occupants, and even then, it was only snarky remarks made about Derek and Bonnie's relationship. John refused to speak to Bonnie before she told him the truth about her summer.
One night, at a silent dinner, John was staring at his plate. "Was it drugs?"
"What?" Bonnie asked.
"Did you spend your summer doing drugs?"
"Probably, if she slept with Derek Hale." Stiles muttered.
"No!" Bonnie yelled in disbelief and stormed away.
During week three of Cold War: Stilinski edition, Bonnie passed Stiles' door, which was open and she paused as she saw a familiar face in a picture.
"Who is that?" She broke the silence, surprising her brother with her presence.
"What?" He said slightly irritably.
"The girl. In the picture with Derek, Scott, Isaac, and you and other people. That blonde girl." Bonnie pointed. She knew that face. She had met that girl. That girl passed through her weeks before.
"Why do you care?" Stiles said hostly, not wanting to speak about the pack with Bonnie, nor how Erica and Boyd were dead.
She snatched the picture before Stiles could do anything and bounded out the door. "Hey!" Stiles yelled and chased after her.
"Dad!" She yelled. She placed the framed picture down on top of the files he was looking at. "Who is she?" Bonnie asked, pointing.
"Dad! She just-"
"What are you talking about?" John asked, confused.
"That blonde."
"That's Erica Reyes."
"How did she die?" Bonnie asked, not considering the possibility that anyone wouldn't know about her death.
"What do you mean? She's just missing." John glanced at his son and shut his eyes. Stiles hadn't told him everything, he surmised.
"Oh. I just assumed." Bonnie backed out, realizing her mistake, before she dodged Stiles and ran back to her room, locking the door.
"Stiles?" John asked tiredly.
Stiles glanced away to make sure Bonnie couldn't over hear them. "She was murdered by the Alpha Pack for refusing to kill Derek."
"Alright." John nodded, defeated.
Bonnie was at Derek's apartment taking a bath when she was surprised. "Not now." She groaned. "Seriously, my boyfriend is in the next room over." She knew she couldn't ask this ghost not to be at peace. "Qetsiyah, you are such a bitch. Worst ancestor ever." She mumbled. She sighed. "It's alright. You can be at peace." She told the ghost.
As the ghost approached her she held her breath and went underwater, hoping Derek wouldn't hear her anguish. She felt bad enough that whatever tentative relationship he had with Stiles and Scott had become further strained because of their relationship.
She writhed in pain for a moment, and as she held herself under, she felt water being splashed over the edge.
Derek was in the next room working out when he heard Bonnie in the next room. He halted his movement as he tried to listen. She was in the bathroom alone and he didn't know who she'd be talking to. When he heard water splashing noisily, he ran into the bathroom, to see Bonnie under water, experiencing something that looked like a seizure. But she was holding her self under. He shook the thoughts out for the time being and rushed over to her, pulling her out, holding her by her shoulders.
"Bonnie!" His eyes were wide as she shook.
"Derek," She asked. "What are you doing here?"
Derek couldn't believe she was acting like nothing had happened. "What the hell, Bonnie! You were drowning yourself!"
"Oh please, I was not." She scoffed.
"What was going on?"
"It was nothing, Derek, I'm fine." At his incredulous look, she insisted. "I am!"
"C'mon, let's get you to the hospital." He tried helping her out, but was surprised at her resistance.
"I'm not going to the hospital, Derek. I am fine." She tried reassuring him.
"Bonn-"
"No. Derek."
"Fine." He let go of her roughly and went across the room and sat against the door.
"What are you doing?" Bonnie laughed.
"I'm making sure you don't drown as you take a bath."
"Derek, you are being ridiculous."
"Like your brother wouldn't relish the moment your dad arrested be for manslaughter."
"Me drowning wouldn't be manslaughter. If anything it'd be negligence or something." Bonnie shrugged, but seeing her boyfriends unamused look, she sighed. "C'mon, have some fun. You could use a bath after working out, anyways, Derek." Bonnie attempted, but Derek looked away, refusing to look at her.
"Fine." She shrugged and leaned back. "The silent treatment is totally my game." She had been a ghost for months. The silent treatment was nothing she hadn't experienced.
She was towel drying herself off, when she heard her phone ring. She walked past Derek, still not talking to each other and frowned at the caller id.
"Hello?" She asked.
"Hello, Bonnie." The voice greeted.
"Elijah?" She asked, surprised and confused. She walked away from Derek and told Elijah, "One moment." She turned back to Derek. "I've got to take this. It's an emergency." Well, she figured it would be for an Original to be calling a Bennett witch, or former-witch. She walked back into the bathroom, but locked the door before Derek could follow. She turned on the shower to drown out anyone listening into her call, supernatural or otherwise.
"Alright, what's going on? I'm not a witch anymore."
"I'm aware, Bonnie." Elijah said, slightly amused. He sighed. "We need to know if any witches have passed through you since you've been back."
"What…how?" Bonnie did not know how the Originals found out about her new status as Anchor.
"My dear brother had an interesting rendezvous with Miss Forbes."
Caroline. Bonnie filed that information away for later. "How would I know if they were a witch, Elijah?"
"Something happened in New Orleans. A harvest. Four girls were sacrificed, but were supposed to come back. A friend, Davina, was one of those girls. She's sixteen, dark hair, about your height."
"No one's found me with that description."
"Thank you."
"I'll let you know if it changes."
"Have a good day, Bonnie Bennett."
"You too, Elijah." When had they become amicable? She ended the call and shut off the shower before unlocking the bathroom door and bypassing Derek, who seemed to forget their earlier fight.
"Who was that?" He asked, following her to their room.
"A friend. Something happened and I need to go do some research." She wanted to find out what type of 'harvest' required the sacrifice of four teenage girls.
"Bonnie-"
"Derek. I don't have time for this!" She said, exasperated. "This isn't something that I can do here and it's nothing that can wait. And I'm one of the only people with accessible information to look for this."
"What is happening?
"I can't tell you. it's private." She began walking out the door, now dressed.
"Bonnie, if you walk out that door-"
"We're over?" She turned back momentarily forgetting her task.
Derek sighed. "No. But I will be upset and worried."
"And I'll make it up to you." She ran back and kissed him before apologizing. "Sorry, but I do need to go." And didn't let him say anything as she ran out the door.
