Analogical

Virgil: Sorry to ruin that for ya....

Logan: You didn't ruin anything.

Analogical is the slash ship between Logan "Logic" Sanders and Virgil "Anxiety" Sanders from the Sanders Sides fandom.

Canon
Virgil and Logan are two of Thomas' sides. Virgil is a former Dark Side, now Core Side, who embodies Thomas' anxiety, and Logan is one of the Core Sides who embodies Thomas' logical side.

When Virgil was first introduced as the antagonist, Logan held a distaste towards him, believing Virgil making Thomas anxious was exclusively a bad thing. However, overtime, Logan is shown to grow relatively friendly with Virgil, especially after "ACCEPTING ANXIETY, Part 2/2: Can Anxiety Be Good?" where Virgil was formally accepted as a side.

While Logan and Virgil had a full video dedicated to them arguing, ("My NEGATIVE Thinking"), Logan admits that "While [Virgil] may be wrong about a lot of things, [he] do[es]n't necessarily mind [his] company."

In "My Personality Q&A", when asked to compliment the other Sides Virgil says, "[He] understand[s] reality better than the other guys, and that is comforting."

Logan and Virgil consider themselves more grounded in reality than the others, and while Virgil is inherently anxious about that very reality, there is a mutual understanding between the two.

Fanon
The ship between them started picking up steam after "My NEGATIVE Thinking", with fans exclaiming that the relationship is relatively healthy, with the two balancing each other and encouraging the other in the ship. A major example often being brought up would be how Logan agrees with the majority of what Virgil has to say and noticeably seems to stand up for him, stating things such as "you're right" or "he's got a point".

Fans of the ship appreciate how the relationship between the two are not just "You're adorable" or them looking "fondly" at each-other but it's also them saying "Wow, that's a good point, let's come to an agreement on the issue and better Thomas".
