Explanations
Spike and Bumblebee friendship

"So what is love then?" Spike nearly choked on his sandwich.
"What?"
"This love thing. What is it?" Bumblebee asked again. They were both sitting outside the Ark, up on the rocky outcrops overlooking the road below.
"How do you mean?" Spike asked, desperately trying to avoid the question. It was only fair though. When he'd first met the Autobots, he spent days asking all sorts of questions, most of which were probably incredibly irritating to them, but to their credit, they didn't complain once. He'd had several of them in fits of laughter with some of his questions, even managing to raise a smile from Prowl. Bumblebee looked down at his friend.
"Well, what it is?"
"Erm…" Spike paused, trying to think of the best way of describing such a complicated emotion. "It can come in many different forms."
"Different? How can it be different?"
"Well… take me and Dad for instance. We love each other, but it's different to the way I feel about Carly." He blushed at mentioning Carly.
"How?"
"Well, I love my dad because, well he's my dad."
"So you love him because you have to?"
"No. It's more like… well, it's because he's my dad." Spike faltered for an explanation. "It comes naturally. Where as with Carly it's completely different. I love her because I've got to know her. And she's amazing."
"She is." Bumblebee agreed. "So you could say that I love the guys because they're like my family, but if I found someone special, it would be a different sort of love?"
"Exactly." Spike breathed a sigh of relief that his friend had caught onto the concept of love so quickly.
"Okay." They sat in companionable silence while Spike finished his sandwich. He'd just picked up an apple when Bumblebee spoke again.
"So what's sex?"
The apple went rolling down the cliff side.
