Was Allen's arm in Rinali's dream as well? I mean, if it didn't break there, Allen's arm will probably survive. Plus, taking apart Allen's arm AGAIN only after one grand battle is too quick, the plot will turn boring if it did occurred.
I think either Rabi or Allen died to get Rinali to power up. She does care for both of them... well maybe more for Allen than Rabi but still.
Maybe: Tikki kicked Allen's ass. Rinali powered up. Rinali kicked Tikki's ass but got injured at the same time. Rabi saw the situation and have another power up as well. Or some other chain reaction like that that shows the Allen-Rinali-Rabi connection :]
...Except if this occurred Rinali's dream wouldn't make sense anymore. Boo.
