Jovian ‘comets’ i.e. icebergs? Martian-like rock ice for comet 67P?

Might it be a just so argument that we saw a comet crashing into Jupiter? Or does it indicate a larger data base and more common incidence? How likely (easy) is it for Jupiter to capture a comet? How is it de-stabilized from orbit?

Alternatively, might such ‘comet’ represent just large sections of ice (i.e. ‘icebergs’) breaking off from moon(s), with quick resurfacing? Then stronger gravitation of Jupiter predominating over it’s moons’ negligible gravity? Might it be sufficient for just spontaneous fracturing of moon’s ice surface, and resultant release of ‘icebergs’ ? Might the heat content of such large ‘icebergs’, or frictional collisions, account for infrared signature detected for such supposed ‘comet’? Might this represent a more plausible scenario than Jupiter catching comets? Might continuous observation from orbit, of our gas giant Jupiter, be worthwhile for this and other reasons?

Likewise might Pluto’s major satellite Charon, and/or other satellite moons, represent a breaking off of ice from Pluto rather than any less likely capturing of a body? Thus is Charon just a broken off large portion from Pluto; or is such satellite too large?

Might ice from short period comet 67P be compared to Jovian and Saturnian moons’ ice, and to Pluto/Charon ice? If 67P comet ice is just from early solar nebula, then might it represent 4 Byr old Martianlike rock ice, with essentially covalent hydrogen bonding for between molecules? Infrared spectroscopy, looking at (and earthly comparisons) hydrogen bond?
