Holly's Links
Holly knew Missile prior to him 'dying' in DRcade2 - the two of them had been dating for some time, and was one of the very first people that Holly could soften up around. Holly knew that Missile had been through a lot as well, and rather admired his somewhat-unhinged desire to take revenge on Peony.
However, with Missile unable to recall their past, and thus their time together, Holly isn't sure how to navigate things from here - it's VERY complicated, to say the least.
Prior to his past self's 'death', Missile often confided in Holly, being one of the very few who he felt comfortable around. Their time somehow brought the two into a rather tight relationship...and even after losing his memories, Missile can tell that something had gone on between the two of them.
That said, as he doesn't really remember what that something is...perhaps to avoid making Holly more hurt, he keeps his distance from Holly.
Initially unsure what to make of Michi, especially due to their ties with Hazel, who had decided to deflect from the game. But as they came to terms with why Hazel acted the way he did...Holly feels a sense of guilt for 'killing' Hazel.
Post-game, Holly quietly vows to keep an eye on them, perhaps because of their shared struggles with knowing someone who lost their memories. One of the very few that can get them to show any level of 'true' emotions, rather than 'mask' they generally show around most folks.
Holly sees Nikola as both fun to tease, and an important figure to respect, especially after the events of the game. They're the person to go to whenever they wish to seek more information about the rogue organization members, and vow together to save as many innocents as they can from this new game's 'despair side'.
Nikola knows that, despite their sass, they can trust Holly a fair deal -- and are torn when they have to decide between letting them go free (at the cost of the players) and letting them forget.
But in the end, with the help of the other players, Holly manages to escape the game with memories intact -- and perhaps because of this shared situation, Nikola wants to do whatever they can to keep it that way. Their mutual desire to stop the rogue members of the organization eventually brings them to once again play the game, though Nikola, claiming the game is 'cursed as all hell', provides support for Holly on the sidelines rather than play directly.
Holly enjoys Kenji's company, both inside and out of the game. While he won't admit to it openly, they're the person who's helped them cope with many of their other friends forgetting who they are, and instead show it through ample teasing. Lucky for Holly, Kenji doesn't seem to mind the teasing at all, and especially when the two have to play DRcade once more, end up having quite the act when together.
In the past, Warden helped Holly -- among the other assassins -- by providing a quick getaway when things get tough. And over the course of the game, though they didn't know at first that Wisp is Holly, when they cotton onto the fact, they become troubled about them possibly losing their memories.
Post-game, when Warden decides to assist Nikola with finding ex-organization members, he ends up working alongside Wisp often, and have formed a fair level of trust between the two. When this eventually brings them back to playing DRcade again, Warden adopts his 'serious, quiet' persona once more, often whispering to Holly rather than speaking outright to others.
As Shuu, they openly talk about Indu being their 'cute mascot partner,' and use that to justify choosing them during Blind Trust Fall. However, Shuu knows Indu far more than they jokingly seem to let on, and would do anything to make sure they're ok (namely for Nikola's sake), even if they tend to butt heads a fair bit irl.
Ever since Solstice has made residence in the mansion, Holly is convinced that their presence is just the combined work of Missile, Michi, and Hazel pranking him. Occasionally, when he visits for a longer time, he's able to have a longer conversation with Solstice, usually regarding Missile - but he never remembers who was speaking to once the two part ways.
Holly's so funny to Solstice. Thanks to Missile they've been able to cotton on that he's had feelings for Missile in the past, so they're always trying to find ways to meme on him for it. It's a shame that Holly doesn't really remember their interactions - they'd probably help him more if Holly wasn't so focused on why there's an 'intruder' in the mansion.
