If Rolo and Reeves knew that Lu Zhen was still holding back, even in such a crisis, they would be astonished at his actions and decision. To be able to do something like that could only be described as foolish by the duo. However, it was still impressive that Lu Zhen could already hold on against the 6, without going all out. If he was able to last this long while holding back, one could only imagine what would happen once he goes all out.
As Lu Zhen was having an internal struggle, Rolo communicated with his original teammates. Due to the fact that Rolo's appearance was somewhat sudden, the two different parties weren't able to form a large party to cover them all. Rather than say that they weren't able to, it would be more correct to say that they both never planned on doing such, and for Rolo, this was a very good thing; almost like a pie dropped from the skies.
