[There's a moment of confusion on Rip's features; Leonard had been a newborn when they'd stolen him to protect him from the Pilgrim. But then he recalls that there had been another instance when Leonard went into the past, far earlier on in their endeavors. That is likely the instance in question here, which would make a great deal more sense.

That resolved within his own head, Rip instead focuses on the more recent alteration in question. He nods at Leonard's conclusion, all of it, up to and including the fact that one day everyone else might know some part of Leonard's life the man himself won't be allowed to remember.]

...There are a few details that can be reasoned out based on what we do know. [It's dangerous ground, but with Leonard currently being dead in their world? Rip still operates on the assumption he won't be impacting the future somehow.

Or at least the hope.]

Thawne has, or had, a goal that puts him in conflict with the Legends. He claims to have recruited you, no doubt to that end. He would have chosen a time from before you felt any loyalty to the team as a whole, and also one where your better nature hadn't yet--developed, so much as it has.

[He doesn't mean it as an insult; Leonard should be quite aware of how much he changed over the last few years of his life.]

Moreover, if he knew of your death at the Oculus, and he well might, he would've known that we wouldn't have been able to attack you easily. Not only would defeating you have to be done in such a way to not alter the timeline, but any of us present for that event would likely hesitate. Strategically, it's a sound move on his part.

[An admission made somewhat begrudgingly; Rip does not like the idea of this particular play. But what follows next? Is much easier to say.]

But I know Eobard Thawne, Leonard. His only intention for you would have been as a weapon. A tool to use for his purposes.
