The problem with Sommers being defeated is that would essentially mean Gaban is capable of taking care of the Holy Knight threat by himself
Which i expected him though. They never seen as such a high threat considering the numbers we got compared to them and their showings weren't impressive enough for me to think they could actualy do something against Gaban.
After the chapter before this one, i was wondering why Oda is sending Gaban in like that, since he should be too much for the HK. And that's what we saw this chapter, he is clearly too strong for them.
Now could a hostage situation happen? Sure, wouldn't be a fan of it though. I mean they already got Colon as a hostage lol - but do they know Colon is Gabans son? Maybe it's gonna be something stupid like Colon screaming ''Father'' when he sees him....
