don't worry, Nobodyman. You could always use the Z-Shield! It protects you from harm! (funded and copyrighted by Kuro No Kishidan a.t.b 2017 - 2019)
Yeah, a good idea is 'tweaking' it. Kallen would be in no shape after defeating the Merlin... But with airbags/aircushions, she wouldn't had received as heavy damage. Still making her feat for active duty (sort to speak)
Bonzo simply is emphasizing that regardless of what Lelouch wants, Kallen is there for either a crutch or a one woman army. Though Bonzo was alittle off-track, it seems fixed now, or will be in the near future.
