I don't think your reasoning is wrong, but why was Gauche so surprised that Lag saw all of his memories in the prologue then?

edit: If you're talking about the latter part of Episode 1, Lag saw Gausche's memories because Gausche used his own Heart to heal Lag's depleted one when he accidentally loaded it ans shot a massive amount.

@ Episode 2, 1:40, Gausche wasn't surprised at all to see Lag knowing some of his past as a side effect of healing.

I haven't seen any other instance where Lag saw Gausche's memories.

In Episode 2 against the Buckers Gaichuu, they saw each other's memories. That can be explained in that they both loaded the shot. Gausche said "Shindan loaded", while Lag was steadying the gun. Then they got separated, Lag's eye resonated and shot the Gaichuu. If Gausche's fragment was loaded already into the gun, then it would explain why both memories were shot.

As for the "surprise", in episode 1 Gausche was scratched by the shot. The look on his face could be attributed to the shock of getting hit, plus the general awe at seeing something spectacular. He was pretty composed after that. He wasn't going "wtf was that??" at least.

In episode 2, he was surprised at Lag's eye, and that Lag's heart resonated with his own while he loaded his own Shindan for the second time, as per his comment after the battle: "You even resonated with my heart."
