Portraying the perky and quirky computer whiz with a knack for role playing, comic conventions and sisterly love for the Winchester brothers, Felicia Day's Charlie has certainly made her mark on Supernatural.

So it was really no surprise that Day nailed it again with "Pac-Man Fever."

Charlie always has such a charming and upbeat personality in pretty much any situation. Whether it was creating her own dress shopping montage (I enjoyed Dean's "No's") or trying to play an FBI agent (notice the Aliens reference?), she's continued to prove herself as a positive addition rather than a bland minor character.

Certainly Day brings Charlie to life, but writer Robbie Thompson, who has written all of Charlie's episodes, has continued to expand upon the character.

We finally learned why Charlie has been on the run so long, in addition to the fact that she's been trying to care for her mother in the hospital.

It was nice to see something she was fighting for, even if the whole point was that it was time to let her mother go. A really touching scene with Charlie reading "The Hobbit" one last time was a good way to close the episode out.

Truly, combing over this episode, there was so much done right.

It was good to see that even though this was primarily a filler episode, Sam was struggling with the after effects of completing the second trial. Not only did he have some major bed head, but his shooting skills were off (kind of reminded me of James Bond trying to get back in the game in Skyfall).

Additionally, Charlie perfectly hitting the target was a funny contrast.

It also felt fitting that Dean was able to help Charlie let go at the same time she was able to give the brothers some advice on their success as hunters. Sam will get through it all and Dean will be there to help him.

I even loved the mentioning of Chuck and wonder if we'll ever see him again. It was a great callback to the novels that he had been writing about the brothers.

That said, I feel like if anything he'd probably get the same type of mentioning that Garth continually gets despite the fact it feels like forever since we've actually seen him. And yet, even through it all, I still felt somewhat underwhelmed.

Allowing the brothers to get involved with a new type of djinn was fun, but the dream sequence that was a video game felt only okay.

Sure, Dean and Charlie looked like bad asses taking out the killer vampires (loved some of the camera work during it), but it felt rather short.

I was even prepared for some Inception-like rules (you die in the dream, you wake up) and assumed that was how Charlie would escape her loop. Yet, she just decided to stop killing the bad guys and they disappeared? She mentally decided to quit the video game in her mind and let her mom go?

Wasn't that too easy? And where was Pac-Man?

I guess I was expecting a little more from the whole video game aspect.

I'm glad Dean was able to give his brother a hug at the end (he hands those out a lot now, doesn't he?), telling Sam to stay home got a little tiresome. I know Dean won't quit on protecting his brother, but I thought they had gotten on the same page about it all.

This was a decent episode and Charlie is always a welcome character, but I wasn't blown away or overly hyped up by what took place. I think with it so close to the end, I'm really ready to buckle up and drive the Impala towards the final trial. I'm definitely hoping it all comes to a classic and exciting Supernatural finale.
