Pff.  Turn the pointy hat into a hood and give him a plague doctor mask and then you’d have what he’d ACTUALLY wear for Halloween.  He’s a dramatic little shit like that.

And one time he did the shaving cream prank to Sylv, only for Sylv to accidentally activate his glove and give himself a concussion from punching himself in the face.

Now just saving someone's life isn't much of a reason for them to be your best friend of course, but like...  The thing about Ser is that he made the effort.  He went out of his way to learn sign language so that he could talk to Lynette on her own terms.  She didn't even have to ask him to do that or anything, and NO ONE had done that for her before.  They were just satisfied to have her write things out to them.

I guess people are doing a thing where they explain the origins of their character's name so yeah

Serinal doesn't mean anything.  Literally it's a name I made up, and I have never been able to find another character named that.  It's often shortened to Ser, which is like an old timey version of "sir" but it's only a nickname.  Also it sorta sounds like serenade, but that's coincidence.

His last name has more meaning, but it's still pretty simple and actually has nothing to do with his height or build.  That's purely coincidence.  Lamppost instead refers to the fact that an ancestor of his invented the lamppost and made a lucrative business out of selling them, forming the foundation of today's (in game) company, Lamplight Inc. which is still run by Serinal's father and is a computers and technology corporation.

And finally his middle name, Cecania, belonged to his grandmother who he never met.  He doesn't know much about it, and he doesn't know much about her, so he usually just shortens it to "C." on official documents.  If he cared to find out, he'd be surprised to know it meant "free" and, leaning that his mother picked it for him, would probably feel a little bit more of a connection with her.

But on the other hand if he sees someone in pain he'll almost ALWAYS offer them a hand up and try to show them their best qualities and despite the sad backstory he doesn't angst about it AT ALL
