When you're about to rendesvouz with Senya again, I see the cutscene with her fighting some Skytroopers and mentioning "No one should be left alone here". After the cutscene I'm all alone, without a companion and Senya isn't in my list to summon either. And in the following cutscenes, Senya is with me, but then I'm all alone again. Senya is in every cutscene, but I'm playing alone for the rest of the chapter. Playing as a healer, the fight with the Skytrooper Constructor and GEMINI Captain were rather boring; manageable though, but slow...
