Triumph was most likely in a coma after the beating he took from Lung
He definitely tried to talk to Victoria when she showed up, and even noticed March going for the Motoroid before she did. I'd say he was mostly aware of the situation, even if at times that awareness was of nothing more than pain and eldritch alien hell.

I've been thinking about what tinkers might be theorized to exist as a part of the Apeiron Group Theory. So far this is what I've got:
1. The Artist: Specializes in aesthetics and beauty. Their abilities may extend to aesthetic thinker powers which assist in their self-presentation, or they may have directly modified the face of their group ("Apeiron") to posses a supernatural grace of movement and posture. Their work is widely noted to more beautiful than conventionally possible, perhaps indicating a direct ability to generate certain feelings in those who see it. This may further be linked to Apeiron's capacity to generate persistent memetic effects in tandem with certain actions.
Possible Identity: Apeiron, Garment.
2. The Geek: Specializes in Powersuits and Robotics, with an apparent affinity for megaprojects given the sudden appearance of their latest work. Their work has been noted to imitate popular fictional properties such as Transformers and Gundam, but it is unknown whether this is an inherent aspect of their power or a matter of personal preference. They seem to have deployed and piloted their own personal work alongside Apeiron during the ABB Incident, making it unlikely that they are the face of the group.
Possible Indentity: Leet (unlikely) or an unknown related trigger.
3. The Doctor: Specializes in Regenerative Healing and Bio-Augmentation. Their work appears to revolve around quickly healing injuries and allowing the body to sustain itself while under the strain of incredible bio-enhancements. Apeiron's changer-state may be linked to their capacity for biological modification, or inversely Apeiron's human form may be the result of their ability to suppress his C53 physiology. Their abilities in collaboration with others may extend to granting technology regenerative capabilities, as seen when the Gundam repaired itself over time while fighting lung, taking on a vaguely biological appearance at points of major damage. May serve as the face of the group if other members are unwilling to be modified, but this remains pure speculation.
Possible Identity: Apeiron
The Insider: Specializes in Parahuman Power Expression. While this theory is often used as a way to ascribe all of Apeiron's abilities to a single tinker, it is possible that a power tinker is working in tandem with a group as a means of making up for some deficiency on their part; an as of yet unknown trade off for having such a powerful ability. Perhaps their ability to tinker alone is feeble, requiring a willing parahuman to modify or scan in order to accomplish anything rather than simply taking inspiration from power scans, and their collaboration with others allows them a direct framework or foundation to express their abilities. The remarkable stability of Apeiron's work may be due to a direct modification of parahuman power, bypassing the usual maintenance limits of tinkertech. Exotic abilities without an apparent technological source may be attributed to further power-based modifications on this Tinker's part. It has even been proposed that Apeiron's claimed thinker power may be this tinker's increased affinity for understanding the relations between parahuman power and psychology.
Possible Identity: Apeiron

As long as I've got a big post going here I may as well put in another line break and bring this up: Lord mentioned on AO3 that people will likely attempt to edit Apeiron's memetic attack name freeze frames into continuous loop videos in an effort to prolong the time dilation effect.
I'll admit I expected Alchemy to be how Apeiron would get the rest of the population into mad science, but clearly I wasn't thinking outside the box enough. This is gonna be great.
