Turtles' Point of View
A frantic search throughout the lair for their beloved kunoichi friend, definitely couldn't be a good experience to re-live for the Hamato turtles. They didn't think that they were going to have to lose you in this sort of fashion, and in a clearer light of where you could've been heading towards. But yet, they somehow did.
"What exactly is she thinking, that she can take on the Shredder alone?!?!" Raphael demanded in an outburst, slamming one of their bedroom doors.
"Oh, so of course you wouldn't have wanted to go after her, and finish him off yourself?" his younger brother, Donatello, asked him with a sense of prying ambition for an answer from his now ticked-off tsundere turtle.
Raph then punched once at their training dummy with an irritated growl, "Argh! You knowwhat I mean, Donnie!!" he then took a second to take a few calming breaths, "She's going to get herself hurt, or worse." Raphael started to sound more worriedly stressed out right now. Just as much as the rest of his brothers.
The Hamato terrapins then gathered themselves around near their lair's home entrance at Leonardo's word of command, ""Come on you guys, focus! If she's headed for Shredder's lair, then we're going to get there first." he told them in his leadership fashion.
"Get where first?" the turtles suddenly heard the curious voices of their allied human friends, April O'Neil and Casey Jones, as they just came around the corner to visit their terrapin friends.
"Is everything okay, you guys?" April asked them with concern.
"You need us for anything?" Casey added.
With wary looks among themselves, they summarized of what you've 'told' them of your past and where you're headed for now, leaving April and Casey just as horrified as the Hamatos before them. Then this was when Master Splinter entered the scene as well, able to overhear everything that has happened since after dinner-time & during his meditation.
"Is all of this true, my sons? About young (Y/N)?" Splinter asked his beloved children before him, even though he already knew.
"Hai Sensei." they all replied sadly.
"I'm also afraid to tell you all of this, my sons. But I greatly fear that while we all might see (Y/N) as a great young warrior of her prideful clan, I can see that she's still a child facing such great pain as my very own. And, she's also let this vengeance between us and the Foot Clan unnecessarily corrupt her former parents' spirits, from within her mind."
Everyone took in what Master Splinter just said, and that was all they ever even needed to hurry through the sewer tunnels. They were going to find your trail of how you're going to be able to make it ti the Foot Clan's headquarters unnoticed.
But as they were, they saw in horror of what exactly you wrote on those sewer walls with your spray paint, just around the next turn in the sewer tunnels. Each message was written in your head in the turtles', and April's and Casey's, trademark colours. They all at least read things like;
-'This all ends, tonight!'
-'The Norio Clan was without mercy, so will the Foot!'
-'I owe you guys one, so why not now?'
-'My father's death was in vain, but the Shredder's will not!'
-'Like I said before, you'll thank me one day for this Hamatos!'
and also...
-'Once this is done, we can all be free!'
