Well, it relays information in the same way that each of you using a random number generator pre-initialized with the same seed relays information. It doesn't involve faster-than-light communication, is the point. Entanglement differs from classical RNGs in that there is no shared seed; no local hidden variable, as it's called. The measurements are just... correlated. If you're interested in a deep dive on entanglement I wrote a post about it: https://ahelwer.ca/post/2018-12-07-chsh/

This is hard to fully understand. So you can't choose in any way which state it will collapse to during measurement? If that was possible, it would mean FTL communication I guess.
