Son of Jerry and River. Robbie probably reads way too much into things and is bold and often very blunt when speaking. He is good at understanding himself and his own motivations and using that self-analysis effectively.
Robbie literally wants nothing more than to just live a normal average relaxing life but random things keep happening to him and he keeps being disrupted by constant quests of outside obligations and un-ignorable events. He feels he's boring and has no purpose and places a lot of value on being distinct from others. He feels a need to stand out and to be recognized as meaninful and important through this, thus having constant doubts about himself and his self worth.
