It was weird being around so many other Cybertronians. Mesothulas had never been the most social, but he had done okay in crowds. Tarantulas, however, was a different story entirely. He had gone most of his life alone. To suddenly be thrust onto a ship full of very social bots was jarring, to say the least. Overwhelming on the best of days, and panic inducing on the worst.
When he first wormed his way on board, he had a goal. But, Chromedome was clearly another one of Prowl's disgruntled partners. Hurt and scorned by a mech that couldn't see past his own world view. Thus, Tarantulas had lost his taste for revenge. Now, he was stuck on an unfamiliar ship with bots he didn't trust. He wasn't good at making friends, and he certainly wasn't good at blending in. He stuck out like a sore thumb with his cyber-organic frame. There were a few bots, however, that tolerated him.
Rodimus was one of those bots, and was also a horribly entertaining mech to pester. Tarantulas got a kick out of startling the poor Prime whenever possible. Which was exactly why he was situated on the ceiling of Rodimus' office, waiting for the perfect moment to strike. He watched with glee as his victim entered the room, waited several moments for Rodimus to get comfortable, then slowly lowered his upside-down form into view with a strand of webbing.
"That looks important," he announced, purposely speaking loudly to startle Rodimus. That, paired with him suddenly appearing upside-down in front of the poor mech had to get some reaction out of the Prime, right?
