There is also an important question to ask: will neanthals come back?
I doubt roddib forget about Asa Hon's twin so I wonder if he will try to search for them and mainly for eunseom.
Also we know that five neanthals are still alive: nunbyeol, roddib and yiseuroobeu. We have 2 left.
yiseuroobeu was already there since episode 1 so I think the other 2 are the other kid that Ragaz and Asa hon saved with roddib, and the last can maybe be Rakeuneurupeu (neanthal's former leader) since they never found his body.
