Ruddie

Ruddie is the het ship between Ruby and Eddie from the Alpha Betas fandom.

Canon
It's canon that Eddie has romantic feelings towards Ruby, but, she does not seem to reciprocate those feelings back.

Pilot Episode
Before Alpha Team get imported into Red Head Intervention for their new mission, Ruby asks everyone except Eddie if they are okay and comfortable, this makes Eddie make a move by saying "Great day to save the world, huh, Ruby?" with everyone else groaning from his attempted flirting, this sets Ruby off as she rudely responds "Yeah, really great Eddie, four years of training at the farm only to find out I'd be spending my days babysitting a group a guys who make sex-dolls of their co-workers." which breaks down Eddie's confidence, making him embarrassed.

Right after they are imported into the game, Eddie grips his shirt and asks "Are you reading it Ruby?" to which Ruby replies, "I have like ten-billion dollars of monitoring equipment, you don't have to speak into your lapel like it's a 90's spy movie, Eddie.", immediately making Eddie embarrassed and laughed at by his friends, with Buck even asking him "Man, Eddie, Are you worried thing's might be moving a bit fast with Ruby?" to which, Eddie gets pissed about afterwards.

Later, when Alpha Team finally get info about why there is no one in the game from a prostitute, Eddie says "Ruby, are you getting this?", and when Ruby replies "Let me check the two-trillion dollar immersion rig, uh yeah! I'm getting it!" Eddie gets, once again, upset at the response and look's down.

When Tommy kills an enemy who sabotages the train they are riding to a fortress with a shovel, he makes a joke whilst killing him saying "Can you dig it?!" which makes Ruby laugh and compliments him on it, Eddie overhears this and yells, asking why she's nice to everyone else except him, which results to Ruby yelling at him, saying to keep his arrogant mouth off the voice channel.

When Eddie is the only one standing when fighting with Two Buck Chuck, he struggles the urge to shoot him, due to TBC using a prostitute as a shield to block him from getting him, then results to everyone telling him to just shoot him, even making Ruby say "Eddie, I don't care if you kill a fake hooker!"

After Eddie manages to defeat Two Buck Chuck without hurting the prostitute (and without touching the floor), Ruby is slightly annoyed at his antics, even saying "You risked the whole mission, just to save a digital prostitute?" with Eddie replying "It was the right thing to do, and that, Ruby, Is what makes us Alpha Team". After Tommy and Mason make fun of his antics, Ruby smiles, sighs and tell's Eddie "Pretty good day to save the world, huh, Eddie?", to which Eddie replies "Yeah, Ruby, Yeah It was", but the moment is immediately ruined when Buck interrupts it by yelling at them saying there is a giant hole in his tiny legs and that he needs to get out of the game.

Fanon
The ship Ruddie seems to be greatly accepted by the fandom, as people find it cute and some people speculate that Ruby has a secret crush on him, however with some shipping it, there are some who make fun of the dynamic and make fun of how Eddie is a 'simp' for Ruby and how he'll so anything to get her attention or go out with her, there are even some people who think that Ruby was 'jealous' when Eddie was saving the prostitute. As much as the ship is accepted, there are some who despise and don't understand the ship. There are some fans who don't ship it because it is either queer-baiting (Due to Eddie being canonically bisexual, but not showing interest in men, yet) or it's lesbi-phobic (Due to many fans headcanoning Ruby to be lesbian).

There is also the argument that the ship is toxic, as It's seen that Ruby doesn't care at all about Eddie and that she is shown to be mean and hurtful towards him.

Ruddie is the rivalry ship to Rubison and other ships with Eddie, such as Poly Team

Trivia

 * The cast crew of the series has made numerous jokes about Eddie and Ruby getting married, only to get immediately divorced.
 * It's unlikely that the ship will be canon, due to the writers expressing interest about giving Eddie a male love-interest.
 * It's also due to the fact that Ruby is heavily lesbian-coded.
