OK DELTARUNE CHAPTER 3 SPOILERS but i'm already coming up with uh..i guess it's a headcanon? ANYWAYS proceed with caution.
OK SO obviously, tenna & spamton do know each other in some capacity for sure. i still have no clue how but for some reason, spamton specifically (& i guess seam kind of too?) knows people from various other dark worlds.
from the vibes i get, i think they totally worked together during spamton's "big shot" era. & they were probably quite close (haven't decided if i like to think of it as a yaoiful thing or like. tenna being an older brother figure or something.) i imagine that tenna has a lot more experience with "fame" or whatever, especially in the past since CRTs like tenna are quite old, an idea that is addressed in game.
also, this is backed up by tenna saying someone (i assume spamton based on context) was going to teach him how newer technology works & he cried about not understanding emails LOL
BUT LIKE. taking all this into consideration, my personal headcanon (which i think is super cute :^)) is that tenna met spamton...somehow when he first started making it big & they sort of worked together! tenna would do the regular TV programs & shows & then spamton would appear in like...the TV ads :^) & i think tenna would probably have to teach spamton how to present on television & things like that since he's new to it &, in return, i think spamton promised to teach tenna about the newer tech in the cyber world. but tenna feels betrayed because spamton just sort of...disappeared. from his perspective, he probably had no idea about spamton being evicted & forced to live in the dumpster. so now tenna feels abandoned & confused by the sudden loss of his business partner. & i think he personifies his fear of abandonment as spamton because of this (like the "my biggest hater" thing in the susiezilla game.)
from spamton's point of view, he might feel betrayed (as we see from the way he talks about tenna in the sweepstakes) because tenna- much like the addisons- didn't really bother to help or look for spamton when he disappeared. he lost everyone all at once. tenna was one of the last people he had left since the addisons stopped talking to spamton when he first became successful. it explains the way he talks about mike too. (omg. this wasn't an original part of the theory but what if spamton feel like mike replaced him or he feels jealous of his dynamic with tenna or something :^O??? just an extra angsty cherry on top.) despite how irrational it is, since spamton never really made it clear what was going on with him & his "helper" on the phone, he still wishes somebody would've noticed & cared enough to help him out. maybe just subconsciously. i think he hides his feelings about it though anger & an unforgiving attitude towards the people he thought he could trust. ogufhfh
there's not a whole lot of merit to this, but a detail i noticed almost immediately was the tenna's suit has the same colors as spamton's during his big shot era! (as seen in this piece of fangamer merch, he is wearing a red suit with a yellow tie.) & i think this supports the idea that they were a duo at some point & i bet tenna (since he likes to live in the past) never changed his outfit. but omg imagine if they matched suits when they were working together ISN'T THAT SO CUUUUTE??? sorry i'm really normal about this.
i think that's all i have right now. feel free to add on or correct anything :^)
