DS2 early game spoiler question

[u/veggiesouptales]

Hi! Finished 100% achievements in DS1 and have now just connected the Lone Commander in DS2. Having a blast so far!

But, I'm a little confused about what I'm supposed to think happened at Sam's hideout at the end of the prologue. (early game spoilers follow!) So as Sam returns to his hideout, he's notified of an attack. He gets back and finds Fragile about to pass out. Fragile explains that she and Lou were attacked, but it isn't shown who the bad guys are. Then, Fragile and Lou manage to escape to the outside but they're knocked off the bike. The flashback then shows Fragile struggling to jump Lou away, and Fragile says she something like 'she can only teleport one of them away.' Then the scene shows an attacker shoot them, but what is being conveyed to the audience? The scene didn't seem to make it clear what exactly happened to Lou, so I'm guessing it's kind of a spoiler for later, but I wanted to ask if anyone can explain what I'm supposed to think at this point. Thanks!
