Ok going by the answer Link Click has provided us with - namely Li Tianchen straight up being red eyes:
if we are to assume that the twin brother is the one holding all the abilities right now (even if Li Tianchen might have had one before), then that means he probably can
A) Steal someone’s ability
B) Possess a person via a photo of them
C) Mind Control/possess (?) someone by touched/being touched (?)
but if B) is true it had to be Li Tianchen giving the photo to Lu Guang, right?
Because Chen Bin was possessed while he was still in Lu Guang’s hospital room (gives him the wrong phone and walks out) -> that means that person now knows about Lu Guang’s powers -> which logically means they are the one who gave the photo to Lu Guang so he could look into it
But why would he do that?
And isn’t there much more pointing towards it being Li Tianxi who did it:
Chen Bin is notably quite during the hospital scene. Does “he” just not talk or can’t he talk?
The person QJ gives the photo of Chen Bin to, also doesn’t talk
“Can’t lose my good brother” knowing now that Li Tianxi isn’t mentally her physical age could totally mean the drawing and writing were done rather recently and delivered like that to Lu Guang on purpose
Again the person who gave LG the photo doesn’t talk
In the last episode QJ kind of implies that Li Tianxi has betrayed them; might that have been about the photo given to LG and/or her taking Liu Min’s phone?
Li Tianchen asked Lu Guang how he knew their location; if he knew about his powers wouldn’t he have asked more directly about a possible connection?
When Liu Lan gets possessed (most likely) she doesn’t talk and also CXS’s POV switches from Li Tianxi to the mother until he is thrown out. Doesn’t that suggest Li Tianxi possessed her? Probably via the photo she held in her arms?
However there are also things suggesting Li Tianchen has the photography based powers:
When Liu Min, Emma and Qiao Ling were possessed they all talked
All of them must have been possessed via photo; there is no reason to think otherwise
Red Eyes possessing QL in a way straight up admits to having photo based powers
if Li Tianchen is red eyes and murdered those other people why would it suddenly be Li Tianxi doing it for Chen Bin?
Could it be that they both have this ability? If not, can they maybe connect their abilities so Li Tianchen can use the photo based power? Is that why the last person (in the present) we saw getting possessed was Chen Bin? Because now without Li Tianxi, Li Tianchen can’t use the power anymore? Is the stealing of abilities maybe more of a copy without taking it away from the original user?
To me it’s more logical that Li Tianxi was the one who gave the photo to Lu Guang, but it doesn’t quite fit with what we know about red eyes, so I can’t make sense of it.
