[Chase lowers their head briefly when Starmie speaks for Erius; It is definitely a mental toll on them. Then again, being a captive is just a mental toll overall. You lose hope eventually.
Alas, after a moment, they gather their words.]
"Honestly, you make good points. You, that other guy, and the kid have no reason to trust me. Just hear me out, at least."
[They've had a lot in their head for their past few days of captivity. They're sick of being useless.]
"Lumen is my superior. Didn't care for me when I reported I was going to die. Terastalis is the boss and even he didn't bother to come and help me. I overall have no reason to go back. They clearly didn't care for me."
[It's hard to admit that. Terastalis was like a dad to them. Put them under their roof, paid for their education, let them work, let them live their life. Lumen was kind of just, there, but they're grouped into this now.]
"I can help. Given that, if, the communicator you confiscated from me is still here and working, I can reverse a signal or find some properties that track down where Lumen is. Or whoever else."
[They shake their bangs out of their face.]
"Now if it's broken, it'll take longer, but I could figure something else entirely. Even make malware if you– if we– if necessary."
[...did the kid kidnap the tech guy of the team?]
"Take it as a proposal of sorts. For my life. I know nothing about what Lumen and Opaq did to ruin the kid's life– and perhaps more lives– but considering how much the team cared for me, I'd rather be of some use for justice than be a reminder of a dead body."
[That and it's revenge for Chase. They want nothing more than to see at least one of the two people who left them to die suffer.]
