Centering within NewEnvironment

Question

I'm working on a LaTex Class for script-writing. I've come into a problem when declaring a Dialog environment.

\NeedsTeXFormat{LaTeX2e}
\ProvidesClass{exampleclass}[2014/08/16 Example LaTeX class]

\newcommand{\headlinecolor}{\normalcolor}
\LoadClass[twocolumn]{article}
\documentclass{article}
\usepackage{amsmath}
\RequirePackage{xcolor}
\definecolor{slcolor}{HTML}{882B21}
 % needed for its \numberwithin command
\newcounter{panelctr}

\renewenvironment{boxed}[1]
{\begin{center}
        #1\\[1ex]
        \begin{tabular}{|p{0.9\textwidth}|}
            \hline\\
        }
        { 
            \\\\\hline
        \end{tabular} 
    \end{center}
}

\newenvironment{panel}{%      define a custom environment
    \bigskip\noindent%         create a vertical offset to previous material
    \refstepcounter{panelctr}% increment the environment's counter
    \textsc{Panel \thepanelctr}% or \textbf, \textit, ...
    \newline%
}{\par\bigskip}  %          create a vertical offset to following material
\numberwithin{panelctr}{section}

\newenvironment{character}[1]
{%
    \vfill
    \hfill
    \textbf{#1}\\
        } 
        {

    \hfill
    \vfill
}%
%--------------------------------------------------


\begin{document}
Below this line a boxed environment is used

\begin{boxed}{Title of the Box}
    This is the text formatted by the boxed environment
\end{boxed}

This text is again outside the environment

\section{First section}

Some text before the first algorithm environment \ldots

\begin{panel}
    Some thoughts
    \begin{character}{Character1}
        Hello, This text is again outside the environment
    \end{character}

    \begin{character}{Character2}
        test dialog
    \end{character}
\end{panel}

\begin{panel}
    More thoughts
\end{panel}

\end{document}

Currently the actual dialog doesn't seem to be centered while the characters name is centered. My idea formatting:

It was also be great if there is a way to get the Parenthetical's to align either left or right to the center of the dialog

Just use the screenplay document class. There are more packages and classes for this, see https://www.ctan.org/topic/drama-script

\documentclass{screenplay}
\begin{document}

\begin{dialogue}[looking up]{Joe}
  And the position of the character's name?
\end{dialogue}
\begin{dialogue}{April}
  ALL CAPS, and tabbed to about 4.0 to 4.2 inches, depending upon the
  look you like. Some writers center al characters' name in
  dialogue. Personally, I don't think it matters too much.
\end{dialogue}
