- Alfredo stands 6'1".
- His "Ethnic Trevor" nickname is a jab at how similar he looks to Trevor, while the more fitting "The Sauce" is a reference to the pasta sauce he shares a name with.
- One video had a Fusion Dance animation of Trevor and a jar of the pasta sauce fusing to create Alfredo.
- The main reason he was hired was to oversee live streams for Achievement Hunter and to grow as talent.
- Being a former professional FPS player for many years Alfredo's specialty is any game that has a gun.
- He has been best friends with Tim Gettys since high school. They once ran a coffee shop together.
- After the AH office got moon balls, Alfredo has been constantly hit by them, albeit accidentally.
- Gravity got him nailed once in the groin (he tried jumping so Gavin, the thrower, could nail Trevor but Alfredo came down and took the nutshot instead)
- Another shot would've hit him in the groin (which had been hit earlier that same video), but a bending-down Geoff took this hit instead
- He was a hula dancer who often entered in competitions.
- He was a Biology major in school.
- Due to his skill in Rainbow Six Siege, Alfredo was named the mentor of an Achievement Hunter team for Siege's return to the Git Gud series. Out of nine hunters he could only name five to the team; he eliminated Lindsay, Fiona, and Matt in the first round of cuts (Lindsay and Fiona were due to understandable skill issues whereas Matt was unexpected), then in naming the final team cut Jack (who's primarily a support-class specialist).
- Alfredo was the winner of Minecraft YDYD 2. Unlike the others, he played with a carefree attitude and managed to repeatedly escape danger (Jeremy giving him the nickname 'Mr. Magoo' for it).
