[It breaks his heart to see her become so dejected, as she breaks from him and looks at the ground like she's the most useless person in the world. Tartaglia quickly shoots a look over to Nahida, concern lining his features, before he steps forward to Yoimiya, placing both hands on her shoulders as he bends down to try to look her in the eye.]

C'mon, Yoimiya. Don't be like that. We just have to play to our strengths here to win. Going in recklessly won't win us any battles. I'm still going to need your help, but we must be careful. Columbina is even stronger than I am, and I have no clue by how much. We're going into this practically blind.

[He's not sure if that's going to help her at all, but all he can tell her is the truth- there's no point in sugar coating such a dangerous situation.]

And we don't need to face her right away, either. I need to train you on that sword a bit more, remember?
