skipped gen v because reasons, need clarification:
"In Generation V, TMs have changed from being single-use items to having infinite uses, making them akin to HMs. In addition, when a Pokémon learns a move from a TM or HM by overwriting an old one, the new move takes on the current PP of the forgotten move."
does this mean i can have fire blast with 40 total pp if i replace, say, absorb? or does it just mean if i replace fire blast with giga drain, then giga drain starts with 5/10 pp?
