"who's that?"
Genai shows up and explains things to the entire group who were back at Mary's old job
"Sharepmon an Ultra level digimon...the only one capable of possibly beating UltraMyotismon"
"Ultra level? I thought the highest level was Mega"
"so did we Tai but according to Azulongmon in the right set of circumstances once can reach the Ultra level...but that level was stated to be a legend since such a digimon hadn't been seen since ancient times"
"yet we're seeing one...no two now"
"not quite, you see UltraMyotismon is not considered a true Ultra digimon. He may have the strength of an Ultra digimon and may have Ultra at the start of his name but according to Azulongmon that alone doesn't make an Ultra digimon"
"then what does?"
"he didn't say, all he said was that Mary met the requirements to use the Ultra level, the true Ultra level"
Azulongmon shows up and tells them
"I'll tell you what the requirements are, not only do you have to be a permanent digimon but you must be willing to sacrifice everything for the freedom of the digital world, and as for Mary since she's a digidestined, it bounds Sylipmon to both the real world and the digital world"
"wait so you're saying they have to be willing to sacrifice everything for both the real world and the digital world to meet the requirements?"
"exactly, and they are willing"
"we see"
"look Mary's ready for the final attack"
And they heard an attack that had never been used before and could only be used by Sharepmon
"crest power, dark moon tidal wave"
and suddenly a huge tidal wave shows up and engulfs UltraMyotismon and explodes on contact and when the light disappears Sharepmon is also gone
"where's Sharepmon?"
suddenly Mary's boss's hand hurts and they all see a red mark on his hand. When the digidestined see the mark they all know what it means even the newest group by some instinct
"she's made the ultimate sacrifice"
and the digidestined mourn while the rest of the group doesn't understand until Genai explains that the mark on the boss's hand was Mary's solution to letting her boss know if she was alive or not and modified by Genai to tell if she was in the digital world or the real world. Once those explanations were given the rest of the group there also goes into mourning realizing just how great Mary was
"I wonder what her last few minutes were like?"
Azulongmon actually shows them
minutes earlier
"you're finished UltraMyotismon we'll make sure of that"
"hah you can never defeat me, even now your attacks are only doing slightly more damage then before"
"then that just means we'll have to use an attack that evenyou can't survive, ready Sharepmon"
"Mary are you sure about this? I mean if Azulongmon is right we could..."
"I know Sharepmon, but we have no other choice now"
"and if it kills him but doesn't stop the invasion?"
"it should...for a bit at least, after that if we're also destroyed it's up to the rest of the gang to take up where we left off"
"hopefully they'll succeed"
and so they up and use the ultimate attack
"crest power, dark moon tidal wave"
and so it works and also destroys them while they were saying goodbye to each other
present
"we'll never forget them right?"
and everyone agrees. Several days later during peace time they have a small funeral for the two of them
